ARJ21-700 aircraft limit static load test completed

Recently, the last step of ARJ21-700 aircraft sub wing flap fatigue and damage tolerance test, i.e. the limit load static test, was successfully completed in Yanliang. This was the first completed fatigue test for ARJ21-700 aircraft components, and was also the first composite component fatigue and damage tolerance test for airworthiness verification that was conducted by China.

During the test period of about two years, four limit static load tests, one ultimate static load test and 124000 flights for fatigue test were carried out for the sub wing flap, 10 points of fatigue were introduced in three stages, and the tests were successfully completed at last.
