A. Gaidansky: TsAGI will test the composite wing of the CR929 aircraft
28.03.2023
Ulyanovsk-based company Aerocomposit has completed manufacturing, and delivered to TsAGI for testing, a prototype wing made of polymer composite materials for the Russian-Chinese CR929 wide-body long-haul aircraft. So declared Anatoly Gaidansky, General Director of Aerocomposit JSC, First Deputy General Director of Irkut Corporation during the forum "Composites without borders".
"This year we
completed and have now put to the test at TsAGI
a prototype composite wing for the CR929 aircraft. As you know – this is our joint project with our Chinese partners, which
we are currently preparing for testing and will probably conduct static tests by the middle of this year", he said.
According to Gaidansky, the wing of the CR929 aircraft is much larger than the wing of the MS-21 passenger airliner. The size of the prototype in the chord is up to 6 m, and the length is up to 22 meters. The increase in dimensions in the wing compared to the MS-21 entails different profile thicknesses and, accordingly, completely different design characteristics and strength testing methods, the general director of AeroComposit noted.
Anatoly Gaidansky also stressed that the prototype of the CR929 wing is planned to be shown at the MAKS-2023 air show, so that visitors to the exhibition can see firsthand how serious this design is.
In March 2021, TsAGI completed tests of the CR929 wing model with a crescent-shaped tip for stall phenomena at the wing ends, both at low and high flight speeds.
