Back in October it was estimated at 178 million rubles The head of the Ministry of Eastern Development Alexey Chekunkov at the exhibition-forum “Russia” at VDNKh spoke about the increase in the base cost of the Baikal aircraft. As the official noted, the price will exceed 200 million rubles.  [caption id="attachment_84363" align="aligncenter" width="780"] aircraft[/caption] The base price of the light-engine aircraft “Baikal” will exceed 200 million rubles Alexey Chekunkov explained: I think that taking into account leasing payments, its total cost will be slightly higher than 200 million, however, by lengthening the leasing period, the efficiency for Aurora is maintained. Chekunkov emphasized that the cost depends on the configuration of the aircraft. Let us note that this is not the first “rise in price” of Baikal. Initially, it was expected that the aircraft would cost about 120 million rubles, but in October 2023, the Russian Presidential Envoy to the Far Eastern Federal District, Yuri Trutnev, announced that the estimated price had increased to 178 million rubles.  The light multi-purpose LMS-901 “Baikal” should become a replacement for the Soviet An-2. The nine-seater aircraft can reach a cruising speed of 300 km/h and fly over distances of up to 3 thousand km, and with a payload weighing 2 tons - 1.5 thousand km. The first Baikal aircraft are planned to be produced in 2025.

Certificate suspended November 10 According to the order of the head of the Federal Air Transport Agency, Dmitry Yadrov, Pobeda Airlines, part of the Aeroflot group, is no longer an aircraft developer. This is due to the suspension of the corresponding certificate, which was issued after Western companies refused technical support for aircraft in Russia. The reason for the suspension is violations identified by the carrier in the approval of modifications on the Boeing 737. “Rosaviation suspended the certificate on November 10. “Pobeda” became the first company in Russia to have its aircraft developer’s permit suspended, issued after Western companies refused to provide technical support for Russian aircraft,” writes the Izvestia newspaper, citing the order. The carrier was found to have violations in the approval of modifications on the Boeing 737 [caption id="attachment_83631" align="aligncenter" width="780"] Boeing 737[/caption] The air carrier's press service claims that Pobeda itself revoked its certificate, although the reasons for this action are not indicated in the document. Seven other air carriers have a similar certificate. With the departure of Pobeda, the Aeroflot group was left with two certificates belonging to Aeroflot airline and aircraft maintenance provider Aeroflot Technics. Earlier, the US Department of Commerce extended export restrictions for Russian airlines, including Pobeda. In 2022, Pobeda significantly reduced its fleet of Boeing 737 aircraft from 41 to 25 units. Flights were suspended in order to ensure a sufficient supply of spare parts for the aircraft until the lost supply chains were restored.

Only one airline in the world operates such aircraft, and it is not in Russia As Vzlyot reports, the Voronezh Aviation Plant has completed a set of works to restore the airworthiness of the long-haul wide-body passenger airliner Il-96-300 (CU-T1250), owned by the Cuban airline Cubana. Yesterday the plane flew from Voronezh to Zhukovsky, and soon it should go home to the “Island of Freedom”. [caption id="attachment_83309" align="aligncenter" width="780"] passenger Il-96-300[/caption] After repairs and extensive maintenance, one of the last passenger Il-96-300 took to the skies Cubana has four passenger Il-96-300 aircraft, the CU-T1250 was the safest of them: it operated flights until February 2022. CU-T1251 landed in 2021, CU-T1717 in 2017, CU-T1254 in 2013. It is expected that upon returning to Cuba, the Il-96-300 (CU-T1250) will again enter regular routes. Cubana is the only airline in the world that, until the beginning of last year, carried out commercial passenger transportation on the Il-96-300. Il-96-300s also fly in Russia, but only as part of the Rossiya SLO (that is, such aircraft are not used on regular flights).

According to the top manager, the MS-21 was initially created “using the most modern approaches” First Deputy General Director of the Rostec State Corporation Vladimir Artyakov gave an interview to Rossiyskaya Gazeta, in which he touched upon the topic of domestic passenger airliners MS-21 and SJ-100. According to the top manager, the MC-21 was initially created “ using the most modern approaches ” - unlike the Airbus 320 and Boeing 737, which have been modernized for several decades. [caption id="attachment_81331" align="aligncenter" width="780"] MS-21 aircraft[/caption] “ The share of composites in its design is more than 30%, which is a record among classmates ,” said Vladimir Artyakov. Deputy head of Rostec spoke about the MS-21 aircraft “ The plane turned out to be beautiful, economical and, most importantly, comfortable. The MC-21 has the widest cabin in its class, large windows, and very spacious luggage racks ,” the top manager summed up. The deputy head of Rostec also noted that the main thing for the airliner manufacturer is to meet the needs of the domestic market. “ The priority today, of course, is supplies in the interests of Russia - we must first of all give “wings” to our own country. But in the future, we, of course, count on interest from abroad in both the SJ-100 and MS-21. The capacity of the domestic market is not unlimited, and this must be taken into account ,” said Vladimir Artyakov. Let us remind you that in accordance with the signed contracts, the first two SJ-100s should be delivered to Aeroflot by the end of this year, and Aeroflot should receive the first six MS-21s in 2024.

The exhibition-forum “Russia” started on November 4 Rostec takes part in the International Exhibition and Forum “Russia” at VDNKh. Participants and guests of the event can “assemble” their own aircraft, as well as become a pilot of the Mi-8 multi-purpose helicopter. For this purpose, an immersive panoramic cinema with a 360-degree view was built. Viewers can follow the entire chain of creation of new types of equipment, from the engineering center, where the idea itself is born, to the production of the final product. The film shows the latest developments of Rostec, such as the MS-21 medium-range passenger aircraft, the PD-14 engine, the BAS-200 cargo-delivery drone, the Ansat light multi-purpose helicopter, and the Jupiter-30 unmanned mining dump truck. You can also feel like the aircraft designers of the Il-114 and MS-21 airliners. The interactive game “Airplane Assembly” was created by specialists from the United Aircraft Corporation Rostec specifically for this forum. The game allows you to use the joystick to “assemble” the fuselage of the airliner: select the bow, middle and tail sections, as well as the aircraft wing and power plants. The screen displays a real workshop where promising IL-114 and MS-21 are assembled on stocks. The opportunity to “assemble” promising aircraft Il-114 and MS-21, as well as “become a pilot” of the Mi-8 [caption id="attachment_79635" align="aligncenter" width="780"] aircraft Il-114 and MS-21[/caption] Guests can also see at the stands of various regions models of domestic aircraft SJ-100, MS-21 and Il-96, the fifth generation fighter Su-57 and the transport aircraft Il-76MD-90A. At the stand of the Republic of Buryatia there is an improvised cockpit of the Mi-8/17 helicopter, which is produced by the Ulan-Ude Aviation Plant of the Russian Helicopters holding company. Here everyone can sit at the helm of this legendary car, and the screens inside show bird's-eye views of the taiga and Lake Baikal, which allows you to feel like a pilot. The international exhibition and forum “Russia” takes place from November 4, 2023 to April 12, 2024 at VDNKh

This time the focus was on the engine nacelle The Central Aerohydrodynamic Institute (TsAGI) continues to test a model of the import-substituted Russian airliner SJ-100. This time, experimental studies took place in the T-128 transonic wind tunnel, with the scientists focusing on the “wing-engine nacelle - pylon” combination. [caption id="attachment_71139" align="aligncenter" width="650"] half-model SJ-100[/caption] The half-model SJ-100 was tested in a transonic wind tunnel We tested two such options: one from the aircraft developer (that is, from Yakovlev), and the second - proposed by the institute. In both cases, the researchers studied how the SJ-100's aerodynamic characteristics (specifically lift) changed depending on the powerplant configuration. Which option turned out to be better is unknown. It is only reported that the pylon confirmed its calculated characteristics. [caption id="attachment_71140" align="aligncenter" width="650"] half-model SJ-100[/caption] Let us remind you that the first two production SJ-100s should be delivered to Aeroflot before the end of this year.

The flight lasted 75 minutes According to the UAC (United Aircraft Corporation) and the press service of Rostec, the second flight of the Russian import-substituting SJ-100 aircraft has just been completed in Komsomolsk-on-Amur under the factory development test program. [caption id="attachment_50878" align="aligncenter" width="780"] Superjet SJ-100[/caption] The aircraft made its first flight on August 29, 2023. It lasted 54 minutes, the height was up to 3 thousand meters. The second flight lasted for 75 minutes and took place at altitudes up to 6000 meters. The imported Superjet SJ-100 made its second flight Rostec said: During the flight, the crew retracted the landing gear, checked the operation of the air conditioning and automatic pressure control systems in the cabin, as well as the operation of the anti-icing system of the engine air intakes and the operation of the fuel system in the cross-feed mode with the pumps on and off. During the landing, an automatic braking system was tested with the release of air brakes. A prototype of the short-haul aircraft SJ-100 was manufactured by the production center of PJSC Yakovlev (part of Rostec). As Rostec said earlier, in total, about 40 systems and units were replaced on the import-independent Superjet. To speed up the test program, the prototype uses Franco-Russian SaM146 engines. The second prototype will soon begin a flight test program with domestic PD-8 engines, which are currently undergoing a series of bench tests and flight tests as part of the Il-76LL flying laboratory.
