Abstract

Abstract: This paper presents the purpose of and task requirements for the full-scale aircraft static test of the C919 large civil aircraft. The characteristics and difficulties of the test were analysed. The overall technical implementation plan was drawn from aircraft constraint, test loading and control, measurement and monitoring, damage detection and condition monitoring. The verification results show that the test system is reliable and the technical implementation plan meets the task requirements. A number of innovative techniques are put forward. First, in the comprehensive loading platform design technology, multi-subsystem integration is optimized accelerating the test preparation process and reducing the risk during test preparation. Second, the constraint error transfer control technology transfers the constraint position error to the non-key assessment position, improving the test accuracy in the key assessment area. Third, regarding the two-way loading technology in the fuselage double floors, the loading has been optimized and the loading accuracy of the local loads has been improved. The technical achievements of this study offer a great reference value for future aircraft tests.

Key words: C919 aircraft, static test, overall plan, comprehensive platform, posture control, fuselage loading
