The Russian airline Sukhoi Civil Aircraft, together with foreign companies, has developed a modern short-haul passenger airliner - Sukhoi Superjet 100 (Sukhoi Superjet or SSJ).
It is worth noting that this aircraft model has received EASA - an international certificate that confirms the use of this airliner by all airlines of the world and Europe, which recognize EASA principles as a standard.
Also SSJ 100-95B is the first passenger aircraft in Russia that meets all European requirements for noise level.
Aeroflot is the main consumer of this model airliners. The airline operates 10 different Sukhoi Superjet models on its routes, out of 22 in existence today.
To begin with, let's take a look at the configuration of the Sukhoi Superjet 100-95V airliner and note both the best and worst seats on the plane.
The first three rows seats are located in business class. All seats are quite comfortable, with the exception of seats A, C and F, D in the first row.
There is a partition in front of the 1st row, because of which there is slightly less legroom than in the other rows of the same class.
Seats 6 to 20 row are economy class seats. Seats A, C, D, E, F of the sixth row are the most comfortable and comfortable in their class. The listed seats have earned the title of the best economy class seats due to the free space in front of the seats and the most convenient location.
The places of the last row ( 20th row) should be given special attention. It is in this part of the aircraft that the differences between the complete sets of the AA and AF airliners are observed.
In configuration AA behind 20, closets and technical rooms are located, so the seats in this row either do not recline at all, or their folding function is very limited. In addition, people will constantly walk near the toilets, and sometimes a line of them will form. These places can be called inconvenient.
In configuration AF - the distance from the last row to the bathrooms is slightly increased. In addition, row 20 seats are absolutely indistinguishable from other economy class seats. Although, walking past you will not stop.
Note: If you are not sure which aircraft you will fly, select the last row only if there are no other options.
- Check out the required aircraft configuration on the Aeroflot website;
- Choose good places for yourself, taking into account the above recommendations;
- If you have any difficulties in choosing tickets, seek advice from qualified representatives of the company.
Today's note is a short overview of the Russian Sukhoi Superjet-100 aircraft, hull number RA-89005. The SSJ 100 aircraft, painted in the colors of the SkyTeam air alliance, was handed over to Aeroflot on March 5, 2012. My flight on it took place on March 30, 2012, that is, more than a year ago. At that time, only 8 such machines flew in the world (now about 20). I will share my personal impressions of the plane. Better late than never, as they say.

Salon SSJ 100 is available in two versions for ~ 75 and ~ 95 passengers. Superjet belongs to the class of regional short-haul aircraft, i.e. designed for medium and short-range flights (up to 2,400 kilometers). But there is also an option with an increased flight range. The layout of the economy class cabin is narrow-body - 5 seats in one transverse row, separated by a passage (3 + 2).

As soon as online check-in opened on Aeroflot's website, I checked in on the first row after business class.

Pay attention to the plane diagram, this row has the greatest legroom.
// glazelki.livejournal.com
Even with the toe of an outstretched leg, it is impossible to reach the seat in front.
// glazelki.livejournal.com
The rest of the chairs are also very comfortable to sit. The row spacing is as decent as it can be in economy class. For me, as a passenger, this is one of the key aircraft characteristics.
// glazelki.livejournal.com
The salon was completely new. So clean that it shone straight. Finishing on the level. Let's go over the main components.
Individual panel. LED bulbs, shine brightly. The buttons on the panel are simple, but they are pressed softly and pleasantly.

The designers succeeded in ensuring that the size of the shelves corresponded to the size of the shelves of liners with a large fuselage diameter, such as the medium-range aircraft of the A320 family. Note that the drawer is deeper above the three chairs. So if the "carry-on" is so huge that it does not fit on the right, you can ask the neighbors on the left to stay over them.

If the cabin is to the eyeballs, and each passenger has a bunch of things with him, there will not be enough space in the carry-on compartment for everyone. However, this is not a problem of a particular aircraft, but a feature of the entire economy class.

Results.
What can I say? The flight took place in normal mode and seemed quite comfortable. Nothing was more annoying than usual. At the same time, the cabin of the SSJ 100 does not differ in outstanding performance from the cabins of other aircraft of a similar class that I have flown. The only noticeable plus is the pleasant novelty of the interior. The old Bombardiers and Embrayers have, in comparison with the newest Superjet, increased grease.
It is not for me, an ordinary passenger, to judge the tactical and technical characteristics, the cost of maintenance and the economic benefits from the operation of the aircraft, but the profile specialists of the airlines. But still I will say a few words about the project itself. First, I fully approve of the use of imported components in the aircraft development process. International cooperation has improved the quality and guaranteed the success of the project as a whole. But the indigestible Latin "Sukhoi Superjet 100", which has become the official name, on the contrary, is very confusing. As a wish, I propose to name the next new model of the Russian aircraft in Russian.
And secondly, the SSJ 100 was launched on a domestic assembly line and is produced in large quantities, for the first time in the modern history of Russia. A solid order book for the liner already amounts to 179 units. As the number of Superjets increases, I hope the number of interregional traffic will grow, which we, the inhabitants of the regions of a huge country, are so lacking.
The Sukhoi Superjet 100 is not just a Russian aircraft, it is Russia's national pride. To go from the first test flight to multi-billion dollar contracts in just 5 years, and this is after the collapse of the USSR and the collapse of the aviation industry, this is a real feat of every employee involved in the creation of the Superjet. Other names for the same aircraft are Russian Regional Jet, or SU95 (SU95), call it what you want, but I fell in love with this aircraft.
Typical Cabin Configuration of Sukhoi Superjet 100
Characteristics
As you can see, the plane has 18 rows of seats, the first three of which are business class. The plane has two toilets at once - one per class. The galley is located in front of the aircraft. There is a modification of the aircraft without a business class, there are 20 rows, and in the left row, where there are two seats, one row of seats is less - the first row is missing. This is how the aircraft cabin looks like in 3D:
As statistics show, two people fly more often than three. Pay attention to the left lane - there are only 2 seats. This means you can fly without neighbors. The step between the seats is generally similar to that of Boing or Airbus planes, the feature is in the 3 + 2 seats. Between the seats - 81.3 centimeters, the legs are comfortable. The interior is finished with plastic. The only thing that I did not like was the folding table, modest in size. However, I did not feel - whether my neighbors threw the table from the back row or not - and in another Boeing, all these machinations are strongly given in the back, here I put the Superjet 10 out of 10, the interior is excellent.
But where you are unlikely to get, as a passenger, this is the cockpit. It has a modern design, rather simple, but it is immediately clear that the plane is controlled not by one, but by two pilots. And this is no longer design, it is safety. In addition, the aircraft is able to land both blindly, focusing only on the instruments, and completely without these instruments, focusing only on the visual picture from the windows. Both are extreme, and can end badly. Of course, everything depends on the professionalism of the pilots and the coordination of the work of the ground services, but in terms of safety, the plane lands with and without instruments.

Let's do without comparisons with Boing, Airbus, Embraer and other brands. I'll just say that Superjet is completely competitive.
Brief history of creation
The Sukhoi Superjet 100 appeared against all odds. The domestic aircraft, created using new technologies, and not the old Soviet technology, has been so in demand on the Russian market since the 2000s that it is surprising that the aircraft made its first flight only in 2008. About $ 3 billion was allocated for the development of the aircraft.
The history of the creation of the Sukhoi Superjet 100 fell on 2 of the most difficult periods for the world economy. The crisis of 2008/2009, then the Sukhoi concern, which is the developer of this aircraft, made its first flights.
93 aircraft are in operation in Russia for 2018.

Is it Russian development
The most important point, is the Sukhoi Superjet 100 a Russian aircraft? No, it is not, but it is confidently going towards it. According to the latest data, 50.83% of the materials used for the production of the aircraft were supplied from other countries, the rest is domestic. The largest supplier is the French company PowerJet, which accounts for about 35% of materials.
However, the development itself is Russian. Concern "Sukhoi" is gradually moving towards not only reducing the share of foreign materials, but completely reducing it to zero. Just think, in 2013, the share of foreign materials was 74%, and in 2014 it was just over 50 percent. Unfortunately, the data for 2015 is not yet available, but they will certainly show that the percentage has decreased even more. This is one of the priority tasks of the concern in terms of production.
Sukhoi Superjet 100 price and competitor comparison
The price of the Sukhoi Superjet 100 aircraft was not published in open sources, but we received information about the conclusion of a contract by Yamal for 20 aircraft, with the disclosed amount of the contract - about 45 billion rubles. The cost of one aircraft is 2.25 billion rubles. For ease of comparison with foreign counterparts, we will translate everything into dollars at the conditional rate of 65 rubles per dollar. It turns out that the cost of one Sukhoi is about $ 35 million.
What about the competitors? For example, a Boeing 737, roughly comparable to the Superjet in its LR configuration (flights up to 4500 km), costs $ 57.5 million before being imported into Russia, and if it is officially registered with a Russian company by paying duties and VAT, the price of the aircraft rises to 81 million dollars. Just compare, 35 million versus 81 million. More than doubled. The price of the Airbus A-319 is $ 63 million, all taxes paid, the difference here is less, but also significant.
Airplane buyers
The main buyer of Sukhoi is Aeroflot. In 2011, a firm contract was signed for the supply of 50 Superjet 100 aircraft. And by August 2015, 30 aircraft have already been delivered, the remaining 20 are in production. But Sukhoi does not live alone with Aeroflot; there are other Russian and foreign buyers. In Russia, 10 Superjets were ordered from Gazpromavia, all the aircraft have already been delivered.
16 aircraft have already been delivered to the Mexican company Interjet. They liked the planes so much that 14 more planes were ordered. 
The future of the Superjet 100
Today, the main competitor is the Boeing 737. And this, by the way, is the most popular passenger aircraft in the world. According to statistics, one Boeing 737 sits down every 5 seconds in the world. Of course, it is still necessary to grow to such numbers, the Boeing 737 began to be sold in the 68th year, and since then has undergone a lot of changes and modifications, because the Boeing company also does not stand still ... Although, given the price of the Superjet, Sukhoi will definitely be able to compete for customers not only in Russia, but around the world.
By 2025, experts predict the expansion of the geography of the aircraft's distribution to 26 countries, and these countries are already known, as they have shown interest. If we manage to get contracts from European companies, which is problematic due to the sanctions of 2014, the geography could expand significantly.
The Asian market is growing at such a pace that within 2 years it will surpass the American one in terms of the number of people transported. This market is a priority for Russia, negotiations are underway with Asian carriers of different classes - from low-cost carriers to national airlines, and in the next 10 years we will have a powerful breakthrough, mainly due to the domestic Russian and Asian markets. And if you are interested in Russian aircraft, we recommend reading about the aircraft -.
During the 12th International Aviation and Space Salon MAKS-2015 United Aircraft Corporation - UAC invited bloggers to visit, who were able to get acquainted with some of the aircraft that are part of the corporation. I would like to talk about the plane Superjet 100... This was my first acquaintance with this car. The first time I got on board this plane was just a day earlier. And today I was given a full tour of this aircraft.
1.
We visited the plane SSJ 100-95LR (RA-89034), intended for the Yamal airline. It is a short-haul passenger aircraft of normal aerodynamic design with a low swept wing and single-fin tail. It is intended for regional aviation. The first regional jet aircraft was the domestic Yak-40, which was also exported. Prior to this, regional transportation was carried out either on Boeing 737 aircraft, which is expensive for such transportation, or on turboprop aircraft. In the late 1980s, Bombardier converted its large Challenger business jet into a CRJ regional jet. It took off for the first time on May 10, 1991, becoming the first state-of-the-art regional aircraft among 50-seat aircraft. Then there were the Embraer planes. They are larger than the CRJ in terms of passenger compartment dimensions. However, the Sukhoi Civil Aircraft Company (CJSC SCAC) has created a regional aircraft with the characteristics of the passenger compartment as on liners intended for hub to hub flights, that is, between major cities. This condition allows airlines to attract additional passengers on their flights.
2.
3.
The excursion was conducted by Aleksandr Viktorovich Dolotovsky, Deputy Chief Designer for Aerodynamics of JSC "GSS".
4.
The aircraft is configured to carry 103 passengers in a full economy class cabin. The seats are installed according to the 2 + 3 scheme. The width of the seats is 465 mm.
5.
The first three rows of seats are set at 33 inches wide. They are separated from the rest of the cabin by an optional curtain, which acts as a class divider. This measure allows airlines to sell the first three rows as business class. This approach is often used in various airlines, when passengers are not much more comfortable on the plane, but business service is given, which consists not so much of seats as of the speed of passing through the airport terminals, baggage claim, and so on. For example, the airline "Lufthansa" uses this. Also, the size of the fuselage of the Superjet aircraft allows, if necessary, to install a full-fledged business class seat in the bow of the seat, which is not inferior in size to those of the A320 or Boeing 737 aircraft. This is the layout of the Aeroflot Superjet aircraft.
6.
Next are chairs in 30-inch increments. The space for passengers here is provided not only by the step, but also by the size of the seats themselves. Despite the fact that these are not Slim Seats, which are now gone and are half as thick, these seats are thinner than those that fly on airplanes produced in the 90s. Therefore, even with a 30 '' pitch, passengers feel the same as with standard layouts with 31 or 32 '' pitch.
7.
The luggage racks in the passenger compartment are chosen so that passengers who have previously traveled on a wide-body aircraft do not have any problems with their carry-on luggage. The overhead bin above the long row (right) is slightly larger than the A320 provides in its standard configuration. The shelves opposite (left) are shallower, but a standard suitcase still fits into it. And considering that this shelf stands above the two-seat unit, there is enough space for everyone. That is, the volume of the luggage compartment per passenger here does not depend on which side he is flying from. Moreover, if we compare the size of the shelf with the direct competitor of the Superjet - Embraer 190, the height of the shelf of our aircraft is almost twice that of Embraer.
8.
The wide aisle between the seats was chosen for aviation safety reasons: Trolley width (food carts) + 1 passenger. This is due to the lack of emergency exits on the wing. This decision was made initially. The presence of emergency exits to the wing limits the designers when forming the layout of the cabin. There should always be an increased seat pitch in the area of \u200b\u200bthe wing exits. Plus, a number of non-reclining chairs may appear in the exit area. At the same time, the aviation rules for the layout of an aircraft with up to 110 seats are allowed not to make emergency exits to the wing if, during special tests for emergency evacuation, passengers meet the limits of special standards. This is about 90 seconds. Thanks to the wide passage, the tests were passed without injuries, and all standards were met. The Superjet aisle width is 510 mm and the cabin height is 2.13 m.
9.
The rear toilet is specially made large. It is equipped with a changing table. This is convenient for passengers traveling with small children. In addition, the size of the toilet is convenient for people with disabilities. There is also a changing table in the front toilet. I was surprised by the presence of an ashtray in the door. It turned out to be a small waste bin, which is labeled as an ashtray by default. Therefore, if you need to spit out the gum, you do not need to glue it to the chair. Airlines spend a lot of money cleaning them. Go to the toilet and put it in the container.
An ATLAS standard kitchen is installed in the aft service area. It consists of modules and on this particular plane is equipped with one oven, a boiler and a coffee maker. It is also equipped with three full-size food carts. Optionally, there can be a large kitchen with four ovens, on which there will already be six carts. This is necessary for airlines that plan to carry passengers long distances and feed them with hot meals. The bow kitchen is equipped with half-size food carts instead of full-size. Optionally, a full-size kitchen with two ovens can stand in its place. Pictured are the feed carts.
10.
All interior lighting is LED. There is not a single incandescent lamp here. LED bulbs are much more durable. This reduces the cost of aircraft maintenance.
Regarding the individual blower nozzles. They are installed in old aircraft because the air conditioning system does not do the job well to equalize the temperature in the cabin. The Superjet is equipped with a modern air conditioning system with digital control. Therefore, individual blower nozzles are not needed here. They are optionally installed at the request of airlines. But the plane is very comfortable with the air conditioning system working.
11.
The portholes installed on the aircraft are the largest not only in the class of regional, but also narrow-body aircraft. The line of portholes is positioned so that passengers can look at the ground comfortably. The designers proceeded from the fact that in flight it is more interesting to look at what is happening under you.
12.
Why such a comfortable salon? This aircraft is designed to be operated on the "Hub and Spoke" system. These are flights between major cities (the so-called "hubs"), and then on regional planes to individual regions. "Hubs" are accumulators, and regional airports are distributors of passenger traffic. Today, a regional jet is usually a fairly serious compromise in terms of passenger comfort. For example, if a CRJ plane flies from a major airport to the region, you will have to put your carry-on baggage in your luggage because it will not fit into the shelves. In Europe, such aircraft are beginning to be squeezed out of the market by high-speed railways. People really don't want to embarrass themselves. Therefore, when forming the technical specifications for the Superjet aircraft, a lot of work was done with marketers. The task was to give passengers the same level of comfort as on narrow-body aircraft and wide-body aircraft in economy class. So that passengers do not feel any loss in comfort. So that they do not have to check in their carry-on baggage, thereby increasing the aircraft turnover rate at the airport. Therefore, today Superjet 100 is a new standard of comfort for regional transportation.
13.
The large cross-section of the fuselage unambiguously dictated very stringent requirements for the level of aerodynamic perfection of the layout. Because the larger the fuselage, the worse the aerodynamic quality of the aircraft. Comfort has a negative impact on aerodynamic efficiency. Therefore, in order not to waste more fuel than competitors, the designers went for an unprecedentedly large wing aspect ratio. The aspect ratio of a wing is the ratio of the square of its span to its area. Today it is one of the few passenger aircraft with a metal wing with an aspect ratio of 10. There are no winglets on the wing. They are placed when it is impossible to make a high aspect ratio wing. Although this idea is being considered and maybe winglets will still appear on Superjets.
14.
The wing is formed from supercritical profiles. When the plane flies at transonic speeds (this is more than Mach 0.75), it comes close to the sound barrier. In this case, on the upper surface of the wing, the air flow speed becomes supersonic. The appearance of supersonic zones leads to the appearance of wave drag, which can increase the aircraft drag by 30%. If we take a standard profile, then at speeds of Mach 0.72 it will abut very strongly and the plane simply cannot be further accelerated. They have been struggling with this problem for a long time. There are different ways. The simplest is to reduce the thickness of the wing profile. Therefore, on all fighters, the wings are very thin and flat. On all old transonic aircraft, the wings are also very thin. But such a wing is very heavy and it is difficult to put fuel in it. Back in the 60s, the so-called supercritical profile was invented. But not everyone knows how to do it well. From the outset, Superjet's creators worked closely with industry institutions. And when the question arose about wing profiling, they turned to TsAGI. As a result, the wing turned out to be fast. The aircraft was optimized to fly at Mach 0.78. He actually flies at a swing of 0.79. As a result of the fact that the designers made such a good wing, in terms of fuel consumption the Superjet 100 with a large fuselage is approximately 7% more economical than the Embraer 190 with a small fuselage.
15.
We came to the cockpit. During its design, a lot of changes were implemented as a result of communication with airlines about how a passenger plane should look like. One of the major changes is the move to an Airbus cockpit instead of the Boeing cockpit originally envisioned. The airlines have made clear their assumptions that the future lies with Airbus concepts. As a result, the aircraft has a cockpit with a side handle and a highly automated control system, both in manual and automatic modes.

In the basic configuration, two FMS (Flight Management System) are installed in the cockpit. It is a computerized flight control system that includes an onboard sensor, receiver and computer with databases of navigation data and data on aircraft performance characteristics. The aircraft is capable of automatic flight immediately after take-off, since FMS provides not only horizontal but also vertical navigation. The aircraft is certified and performs automatic approach in the 1st, 2nd and 3rd categories, including automatic landing.
20.
The aircraft is approved for flights to the area of \u200b\u200bprecise area navigation - P-RNAV (Precision Area Navigation). Area navigation RNAV is a navigation technique that allows an aircraft to fly along any desired trajectory. This is the first Russian aircraft to have such a certificate. At the same time, the certificate was issued based on the results of tests that were carried out in Finland under the close attention of Eurocontrol.
21.
The aircraft can make approaches in vertical navigation mode, when the 3D space trajectory is generated by the Flight Management System using the navigation aids on board. These are two sources of satellite navigation: GPS and GLONASS. Three high resolution inertial systems - IRS (Inertial Reference System). All means of radio navigation: VOR (Very high frequency Omni directional radio Range), DME (Distance Measuring Equipment). In addition, an automatic radio compass - ADF (Automatic Directional Finder) can be optionally installed on board. This is an automatic heading indicator that allows approaches in northern regions. In particular, aircraft with two optional ADFs are delivered to Yakutia Airlines.
22.
23.
The aircraft is certified for operation in the temperature range from -55 ° to + 45 °. Traditionally, tests for low temperatures are carried out in Yakutia with complete freezing of the aircraft. During the tests, the testers showed the possibility of hangar-free operation of the aircraft in conditions of average temperatures below -45 °.
This machine is equipped with an optional weather radar with a wind shear detection system. Plus, this radar has the ability to map and detect turbulence.
24.
A little about the control system. Taking the concept of the Airbus cockpit as a basis, the designers did not engage in simple copying at all. Together with TsAGI, completely unique control laws were developed, which were completely written here in Russia with the active participation of the 15th department of TsAGI - the department of stability and controllability. These laws include not only those features that are already implemented in Airbus, but also a number of those that are only now on the A350. A certain mix was laid on the plane between the Airbus ideology and the traditional plane. The principal differences are that the level of automation here is the same as on the Airbus, but at the same time an autothrottle with actuators is installed on the Superjet for the automatic thrust control function. That is, when the autothrottle is operating, the throttle sticks (throttle control sticks) move, which is not the case on Airbus, where the throttle controls are in the “Climb” position for the entire flight. If the pilots on landing forget to remove the throttle, a sudden increase in thrust begins for them. For this reason, there was at least one A320 crash in Sao Paulo on July 18, 2007. In addition, the Superjet, in terms of flight performance, behaves like a conventional aircraft with a mechanical control system. Airbus has significant differences in its behavior both in the longitudinal and in the lateral channel from aircraft with a mechanical control system. This is the developer's decision. But the Superjet designers decided that this idea was not a good one. Because the pilot begins his training on an aircraft with a mechanical control system. He is developing certain skills. In order to prevent the pilot from finding himself in a stressful situation, such as the fact that the aircraft's behavior does not correspond to his expectations, the designers made the aircraft dynamics in such a way that the pilots did not feel the differences when switching from the aircraft with a mechanical control system to the Superjet. This introduction has very good reviews, both from Russian pilots and from foreign ones, starting from Airbus pilots. Philippe Kasten, who is currently testing the A350, worked for 6 years with the European Aviation Safety Agency (EASA) team for the Superjet certification. He really likes this car.
The glass in the cockpit provides the maximum viewing angle for a civilian pilot. This is important for regional aviation. Since you have to fly to bad airfields in poor visibility conditions. The glass is heated and, at the same time, it is absolutely transparent. The technology was developed specifically for the Superjet. Now the Sully-Gobaine company (France) is the only manufacturer in the world that can produce heated glass with such an area and such a level of transparency.

After getting to know the cockpit and the passenger compartment, we went down the ladder and walked around the plane.

All aircraft design from the very beginning was carried out digitally using the CATIA V5 3D modeling system. This made it possible to analyze different compartments in 3D. In addition, the experience of the team that had previously worked with different aircraft at different times was taken into account. Thanks to this, the smallest details have been worked out. For example, the fuel filling panel flap, which is constantly accessible. The aircraft is made for a very short turnaround time. Time on earth should not exceed 30 minutes. With such a pace, it happens that the hatches are forgotten to close. To prevent it from being blown off in flight, the loops are made in such a way that it is closed by the oncoming air stream.
29.
There is no analog system on the plane. All systems are digitally controlled. The fuel system is also digital. It has its own fuel density meters, which are in the tanks and provide fuel density measurement. Therefore, fuel is taken on board not in liters, but in kilograms. The measurement is performed with high precision. Thus, the crew always knows the exact amount of fuel in kilograms, regardless of whether they brought cold fuel or hot. This is both economy and safety. There are free water sensors in the fuel system. They are designed to detect water in fuel. Traditionally, this procedure is done as follows: samples are poured from the drainage of fuel tanks, into which manganese is poured. In this way, the presence of water in the aircraft tanks is checked. If the car flies with the same frequency as a regional plane, and the Superjet makes 3-4 return flights a day (that is, 6-8 take-offs and landings), you may not even be able to overlook it. Therefore, there are free water detection sensors in the fuel system, which will light the lamp during refueling when it is detected.

The main landing gear of the aircraft are made according to the two-braced scheme. This is usually the case for large wide-body aircraft. It significantly outperforms a single brace in both side impact strength (when landing with a crosswind) and weight. Although the stand itself is heavier, its weight with all the surrounding structure is lighter.

This is a new generation of regional engines. The most modern technologies were used in its design. First of all, this is 3D optimization of all aerodynamic surfaces. Since it is intended for a regional aircraft, great attention has been paid to the ingress of foreign objects into it. All fan blades can be changed without removing the engine from the wing. The engine is built on a modular architecture. This allows most of the repair work to be carried out without removing the engine. If, nevertheless, there is a need to replace the engine, it is changed in 1.5 hours by a team of 2 people.

On the Superjet aircraft, not only the passenger compartment, but also the luggage compartment is convenient. Compare it to the luggage compartment of the Embraer 190, which is less than one meter high. Since luggage in both planes is loaded in bulk, in order to load / unload a flight, a person must be placed there. On the Superjet aircraft, a luggage compartment height of more than 1 meter was specially chosen. This allows the loaders to work in more comfortable conditions. In addition, despite the fact that the Super Hold is larger than the Embraer 190, the height of the lower edge of the luggage compartment is lower. For Embraer 190, this height is more than 2 meters. That is, while standing on the ground, it is very difficult to reach the hatch opening handle without rolling up the ladder. In order to load the luggage of the last passenger, who has just arrived, on board the Embraer 190, you need to roll up a ladder. On a Superjet aircraft, the hatch can be opened from the ground without the need for additional tools.

The percentage of the share of Russian and imported parts to the Superjet design is very well written in this article.
As for production under sanctions, it is difficult to get a definite answer to this question. Nobody knows what will happen tomorrow. And one can only guess about it.
Many thanks to Alexander Viktorovich Dolotovsky for the excursion. And also the United Aircraft Corporation for the invitation.
Work on the Sukhoi Superjet 100 aircraft began in March 2003. It took off for its first test flight in May 2008. Factory tests ended 4 months later, in October, after which the next stage, necessary for the certification of the liner, began. For the first time, the plane took off on a flight with passengers on April 21, 2011. The Sukhoi Superjet 100 short-haul aircraft became the first in the family. Its modification "Superjet" (LR - Long Range) is distinguished by an increased take-off weight and a longer flight range of 4578 kilometers. For the first time, the aircraft of this modification took off in 2013.
Another modification of the "Sukhoi Superjet 100 SV" has an elongated fuselage. This will allow the liner to carry more passengers. Work on the creation of this model began in 2015 and is scheduled for completion in 2018.
By the end of 2017, the number of aircraft manufactured reached 110, while more than 90 Superjets were sold to airlines. These aircraft are operated in Russia, Mexico, Ireland, Armenia, Laos, Indonesia, Thailand.
Sukhoi Superjet is used poorly by Russian airlines. For a number of reasons, it takes at least 2 months to wait for spare parts. At the same time, spare parts for foreign-made aircraft are provided within 24 hours. Because of this, a significant part of the aircraft is idle.
In 2015, the total flight hours of these 25 airliners at Aeroflot amounted to about 9000 hours. The airline "Gazprom avia", which has 10 superjets, 1400 hours. That is, on average, each plane was in the air for a maximum of 25 minutes per day. For comparison, an indicator characterizing the work of "Boeing 737" is given. On average, everyone is in flight up to 15 hours a day.
Best and worst seats in the cabin
The layout of the Superjet's cabin is made according to a scheme in which 12 seats are provided for business class and 75 for economy class. That is, the total number of passengers is 87. Of course, more amenities are available where business class seats are located. Here the chairs themselves are somewhat more comfortable. They are both wider and softer. The disadvantage is that the existing partition separating passengers from the economy class here is too thin. It does not provide a high level of sound insulation.
The best seats in both classes are in the front row. In business class this is the 1st row, in economy class it is the 6th. The plus here is that there are no seats in front, which means that passengers do not recline their backs, causing some inconvenience to those sitting behind.
Another plus is that there is more legroom here, which is quite comfortable on a long flight. In addition, the passengers in these rows are the first to receive food and refreshments. In addition, staying farther from the middle of the cabin, where there is almost always noise due to communication between passengers, is also an additional convenience.
The best places include those in the other rows, marked in the diagram A and F. These places are located at the windows. For this aircraft, they are quite large, conveniently located, and provide a good overview.
Since all of the seats in Business Class are always better than in Economy Class, there is little need to dwell on them. We can only add that in addition to the convenience due to the increased softness of the chairs and their greater width, there is such a plus as the distance between the rows. It is one and a half times more than in economy class.
Passengers behind the partition that separates business class from most of the cabin find themselves in somewhat cramped conditions. Although the spacing between the rows meets the standards, passengers with a high height are still uncomfortable here.
A serious minus is present in places C and D of the 19th row. There is a lot of traffic of those who go to the toilet. In addition, flight attendants are constantly working in the aisle. This also creates inconvenience for the passengers who are here.
The seats located in the 20th row are recognized as the most uncomfortable. The kitchen and toilet are located at a short distance. Passenger traffic is the most intense here. To a greater extent, place D, located next to the entrance to the kitchen area, is not convenient. The difficulty here is that almost every time the trolley with which the flight attendants pass through the cabin, serving passengers, hits either the seat or the passenger. And this is still rather unpleasant.
Pros and cons of the plane
Among the advantages of the aircraft are the latest design solutions and new technologies. Suffice it to mention that the developers took into account the requirements of the FAA (US Federal Aviation Administration) and EASA (European Aviation Safety Agency). In addition, in the course of the work, the requirements and wishes of those who operate the aircraft and are potential customers of the Superjet were taken into account.
The advantage of the new airliner is that it can land and take off on runways A, B, C. This becomes possible both due to its design features and due to the fact that it uses a modern avionics system. Due to this system, the landing of the liner is possible for the liner in adverse weather conditions.
Currently, the "Superjet" does not have any flaws that could arise in its design. Of course, they were at the first stage. However, everything that could adversely affect the aircraft was revealed during its tests. What could not be detected immediately was eliminated within two years (2011 - 2013), that is, in the first years of operation.
Still, some flaws remained. They refer to living conditions. Among them are the insufficient width of the aisle, somewhat increased noise in the cabin, which creates discomfort for some passengers. Business class passengers have an inconvenience - poor sound insulation from the rest of the cabin due to the thin partition.
These disadvantages are more than compensated for. The liner has an unprecedented security system. It uses algorithmic protection to prevent touching the GDP. It is more efficient than mechanical shock absorbers.

Conclusion
Summing up, it can be noted that even with the existing shortcomings, the Sukhoi Superjet is a good aircraft. It can provide transportation of passengers for both short and long distances. Although the dimensions of its cabin are inferior to those of the Airbus A-380, its spaciousness corresponds to this class of airliners.
The existing security system and modern avionics ensure high reliability. At the same time, the prime cost of the aircraft, in comparison with analogues, is significantly lower. We can say that this airliner is another stage on the way to a new generation of aircraft. And his performance allows him to be recognized as the best among the representatives of this class.
