Airworthiness safety verification method of aeroengine based on FTF

Abstract

Abstract:

In order to meet the aeroengine security requirements of CCAR33-R2.75, the method of aeroengine complying with CCAR33-R2.75 based on FTF is proposed. Firstly, hazards and important consequences of engine are selected as top events in CCAR33-R2.75. Then, FTF is applied on security analysis of aeroengines, and Isograph Reliability is employed to draw the fault tree and calculate the probability of top events. The aeroengine verification process is established complying with CCAR33-R2.75 based on FTF. Finally, a certain type of aeroengine is analyzed with feasible results.

Key words: aeroengine, FTF, safety, CCAR33-R2.75
