摘　　要：为了使航空发动机满足CCAR33-R2.75条款提出的安全性要求,提出了基于FTF的航空发动机CCAR33-R2.75条款验证方法。首先选择CCAR33-R2.75中危害的和重要的发动机后果为顶事件,然后运用FTF综合分析法对航空发动机进行安全性分析,利用Isograph Reliability软件画出故障树并计算出顶事件的发生概率。建立了基于FTF的航空发动机CCAR33-R2.75条款验证的步骤和流程。最后对某型航空发动机进行实例分析,验证了该方法对航空发动机CCAR33-R2.75条款验证的可行性。In order to meet the aeroengine security requirements of CCA R33-R2.75, the method of aeroengine complyingwith C C A R33-R2.75 based on FTF is proposed. Firstly, hazards and important consequences of engine areselected as top events in CCAR33-R2.75. Then, FTF is applied on security analysis of aeroengines, and IsographReliability is employed to draw the fault tree and calculate the probability of top events. The aeroengineverification process is established complying with CCAR33-R2.75 based on FTF. Finally, a certain type ofaeroengine is analyzed with feasible results.
