TsAGI specialists do static tests on MC-21 wing torsion box
22 November 2017
The purpose of the testing was to confirm the safety of flight tests of experimental aircraft with strength-designed wing at maximum flight loads accepted for the designing by PJSC “Irkut.”
The wing torsion box nondestructive test withstood the load which exceeded the stated load. The process experimentally confirmed sufficient strength of the wing torsion box at maximum flight loads of the MC-21 within the parameters adopted for flight tests.
