Russia has HIGH HOPES as to producing & exporting Commercial Aircraft

1st Flight of MC-21-300 with much hype

Major Emphasis- COMPOSITE Wing- new materials, new manufacture new design limits?

It’s Aircraft Certification Authority not earn high marks

Russia’s MC-21-300 completed its first test flight and a publicity laden article was published. With typical Slavic pride, Denis Manturov, Minister of Industry and Trade of the Russian Federation, declared this plane’s flight a success and said—

“The first flight of an airliner with wings made of Russian composites corroborates the fact that we have done everything right, the MC-21 program is developing consistently and unswervingly in spite of sanctions and unfair competition.”

Pilots after 1st flightThe below article extols the nation’s exceptional performance based on purely domestic research and development. To underscore its sense of chauvinism, the releasecomposite assemblies and testing site & regimen trumpets its test pilots– test pilot, Hero of Russia Roman Taskaev[1], and test  pilot, Hero of Russia Oleg Kononenko[2], neither of who has any real civil airline test pilot experience.

Never been used before materials AND new manufacturing processes AND a wing with unique aerodynamic characteristics unattainable for a metal wing and based on research by the world’s 185th ranked aeronautical engineering university (see fn 5) —all new from Russia, but worry not certification of the MС-21-300 aircraft is nearing completion. The independent airworthiness review will be completed by the Aviation Register of the Russian Federation established in 2015.

Tass, the government controlled news agency opined in 2019 that Russian “Aviation Safety Review Appears To Be Inadequate”. EASA, in the same year, expressed doubts about the processes, standards and staff involved in certification there. A 2021 crash in Kamchatka highlighted the country’s less than exemplary safety record. These concerns have been flagged since 2012. In 2013 IATadded its concerns about the level of aviation safety in the massive country. The global aviation trade association found: “A flight accident occurs once in nearly 275,000 flights in Russia and CIS countries while the global average is one per 500,000 flights.

IATA concerns

According to the IATA official, Russian airlines lack investments and trained pilots. Permission for foreign pilots to operate on Russian companies’ aircraft is just a temporary tool to cover the deficit.”

Some of these critiques reflect judgments that the Russian operations are deficient, but there are some overlaps as to airworthiness issues. The most direct indicator of the weaknesses in Russian certification is the FAA’s history of Bilateral Aviation Safety Agreements (BASA). Typically, a formal relation is initiated by execution of a sovereign-to-sovereign note and as the two authorities gain knowledge and confidence, the BASA is upgraded.

The FAA and the CAA of the moment  (IAC, FATA, Aviation Register of the Russian Federation) started to acquaint each other with their standards and procedures in 1998. The BASA was recorded in 2016 and since then there have been minor technical changes and expressions of dissatisfaction.

 

This export from Russia may not be greeted with love by the rest of the world.

MС-21-300 airliner with wings made of Russian composites performs its first flight

Today an MС-21-300 aircraft, whose wings are made of polymer composite materials produced in Russia, has performed its first flight. The airliner became airborne from the airfield of the Irkutsk Aviation Plant, a branch of Irkut (a subsidiary of UAC of Rostec State Corporation). The flight was performed in normal mode.

The aircraft was piloted by a crew consisting of test pilot, Hero of Russia Roman Taskaev, and test pilot, Hero of Russia Oleg Kononenko. “The flight mission was fullyof test pilot, Hero of Russia Roman Taskaev, and test pilot, Hero of Russia Oleg Kononenko completed. The aircraft systems were operating normally,” Roman Taskaev said.

MС-21-300/310 is a new generation medium-haul aircraft with a capacity of 163 to 211 passengers. Its key distinction consists in its wings made of composites.

The first flight of an airliner with wings made of Russian composites corroborates the fact that we have done everything right, the MC-21 programme is developing consistently and unswervingly in spite of sanctions and unfair competition. This is a result of accumulating knowledge and expertise in the aviation industry, as well as unprecedented government support. The total amount of funds allocated by the Ministry of Industry and Trade for the creation of a composite wing adds up to 4.4 billion rubles[3]. This Russian technology has a number of advantages over the traditional prepreg autoclave technology, which makes it possible to increase productivity, reduce labour and production costs, provide conditions for forming large parts and high quality of mass-produced products. To date, a composite wing has already been made for two aircraft, and the manufacture of a third set is in progress. We plan to obtain changes to the type certificate regarding the composite wing made of Russian materials in the second half of 2022,” said Denis Manturov, Minister of Industry and Trade of the Russian Federation.

Minister of Trade and Industry

Moscow State UniversityDomestic materials for composite bearing structures of the wings were developed in close cooperation with scientists from Moscow State University[4], Rosatom and aviation industry specialists. The qualification tests of the materials showed that they meet the requirements of MС-21 structure. Wing panels and the centre section of the MС-21-300 aircraft are made at the AeroComposite-Ulyanovsk plant. The wing is manufactured using unique vacuum infusion technology, patented in Russia.

The share of composites in the MС-21 airframe is about 40%, which is unprecedented for medium-haul aircraft. The use of strong and lightweight composite materials has enabled the design of a wing with unique aerodynamic characteristics unattainable for a metal wing. Improved aerodynamics have made it possible to increase the width of the MC-21 fuselage and expand the cabin, which brings new advantages in terms of passenger comfort. MС-21 is the world’s first-ever mid-haul aircraft with such solutions,” said SergeyCEOs Rostec and UAC Chemezov, CEO of Rostec.

MС-21 is focused on the most mass-market segment in passenger transportation in Russia and in the world. At present, the certification of the MС-21-300 aircraft is nearing completion[5], we plan to launch deliveries of it to airlines in 2022. At the same time, tests are underway of MС-21-310 with the new Russian PD-14 engine.

There are six MС-21-300 aircraft in production, intended for delivery to customers. All of them are equipped with wings made of Russian composites. An impressive step forward has been made in strengthening cooperation between Russian aircraft manufacturing plants as part of the MС-21 programme. Centres of competence have been created within the UAC system, specialising in the production of individual units, e.g., Aviastar produces fuselage panels and tail unit for MC-21, and Voronezh Aircraft Plant makes engine pylons and landing gear fairings. AeroComposite-Ulyanovsk manufactures the wing box, and KAPO-Composite – the wing high lift devices. These centres are involved in ambitious projects in the Russian aircraft industry,” said Yuri Slyusar, General Director of United Aircraft Corporation.
