Irkut passed to TsAGI fuselage aircraft MS-21

Long time no hear anything about how things are going at the Irkut to create MS-21. And now the interesting news.

JSC "Corporation" Irkut "transferred FSUE" Central Aero-Hydrodynamic Institute "(TsAGI) experienced a cylindrical compartment of the fuselage aircraft MS-21 to test for life and vitality.

The compartment is made at the Irkutsk aviation plant (IAP) — a subsidiary of JSC "Corporation" Irkut "on the basis of design documentation, co-developed by designers of the Engineering Center. AS Yakovlev, a member of JSC "Corporation" Irkut "and experts IAP.

During the manufacturing process chamber introduced a number of emerging technologies that will be used in the production of experimental and production aircraft.

Compartment delivered to Zhukovsky aircraft An-124 "Ruslan". Due to the large dimensions compartment, its transport performed with the covers technological elements. Experts IAP together with employees TSAGI hold dosborku cover, leak test and a pressure test.

Then, scientists and specialists of TsAGI will start the construction of fatigue tests on the life and vitality. The compartment will be mounted on a test stand, which will be simulated structural loads during all phases of flight and recorded numerous parameters that characterize the behavior of the bay and its elements.

The purpose of the planned tests — experimental confirmation of the effectiveness of inherent structural and technological solutions for the design of the resource type design of the aircraft fuselage MS-21.

Tests of an experienced cylindrical compartment of the fuselage — a large part of the work carried out within the project. Currently, the IAP produced a large number of test specimens, including several types of fuselage panels, transverse and longitudinal joints, cut to test ptitsestoykost etc. In the near future the plant — launch of an experimental batch of four aircraft: three flying machines and one Static test.

The President of the Corporation "Irkut" Oleg Demchenko said: "The creation of MS-21 has passed from the design stage to the stage of manufacturing elements of aircraft design and extensive testing."

General Director of FSUE "ZAGI" Boris Aleshin, emphasizes: "Studies in the central fuselage Aerohydrodynamic Institute rated for approximately two years. During this period, the fuselage of the MS-21 "make" more than a hundred thousand conventional operations. The presence of unique experimental base, which has TsAGI, will confirm and work out the newest designs incorporated in the power scheme of the fuselage of the aircraft. "

For reference:

Creating a new generation of passenger aircraft MS-21 provided by the Federal Target Program "Development of Civil Aviation of Russia until 2015" and is the main promising project of the aviation industry in the Russian segment of civil aviation. Head developer of the MS-21 — The Corporation "Irkut".

TsAGI is the main venue for the tests as part of the MS-21. Here, from 2009 to now being tested aerodynamic models of MS-21, and from 2010 — tests of elementary and structurally-similar patterns of units and details of the new airliner.

During said tests:

?developed and experimentally confirmed the aerodynamic design of the wing of high aspect ratio with higher values of lift-drag ratio in cruise flight;

?A complete series of experimental studies on models of MS-21, including tests at high angles of attack, and in a tailspin;

?experimentally demonstrated the ability to set the wing closely spaced ultra-bypass ratio engines (such as PD-14, PW1400G) with minimal loss of the interference of the engine and airframe;

?odnoschelevaya wing mechanization developed and experimentally confirmed its high aerodynamic performance during takeoff and landing flight.

As part of the MS-21 tests are carried out in the organization "Aviatest" (Riga, Latvia). There in January of this year, given the experimental compartment aft pressure bulkhead of the fuselage with the MS-21, made "Aviastar-SP".

Central Aero-Hydrodynamic Institute. prof. NE Zhukovsky was founded in 1918. Today TsAGI — the largest public research center of aviation and space industry of the Russian Federation, where he successfully solved complex problems of fundamental and applied research in the fields of aerodynamics and hydrodynamics, aeroacoustics, flight dynamics and strength of structures of aircraft. The Institute has a unique experimental facilities that meet the highest international standards. TsAGI carries the state examination of all aircraft being developed in the Russian design bureaus, and gives a final conclusion on the feasibility and safety of the first flight. TsAGI is involved in the formation of state aircraft development programs, as well as in the creation of airworthiness standards and regulations of government documents
