The Central Aerohydrodynamic Institute (TsAGI) announced the preparation of a certification conclusion on the strength of the MC-21 stabilizer based on the results of a complex test program. The customer of the work was PJSC "Yakovlev".
The stabilizer was tested for both overall and local strength. In particular, the tests determined the level of stress state of the suspension units, the stabilizer adjustment mechanism, and the elevator.
The results of the experiments were transferred to PJSC "Yakovlev" for the preparation of a certification conclusion on the strength of the MC-21 stabilizer. In addition, TsAGI is currently conducting strength tests of imported replacement glasses for passenger cabin lights. Studies of cockpit glasses and floor elements of Russian production will start in the near future.
The adjustable stabilizer is part of the empennage, which ensures the stability and balance of the aircraft in all flight modes.
