Abstract
Airplane drag chute opens automatically when the door opens. Based on working principle, failure causes of the accidental open of an airplane drag chute include failure of power source, lack of safe lock depth, resonance of elastic element, and lack of strength and stiffness. Then the article builds the fault tree and raises relevant reliability analysis model. Citing airplane drag chute system of a certain plane as an example, we do the accidental open reliability analysis and raise improving suggestions. The work can provide reference on the mechanism design for airplane drag chute system.
