航空发动机体内减速器的加速等效试验技术

Accelerated Misson Test Technique of Decelerator Installed in Aeroengine

在某型航空发动机机体内减速器上进行３８ｈ的加速等效试验与正常试车１５０ｈ试验的结果相比较，测出其损伤形式与程度均相似，从而证明加速等效试验的有效性。并以之为例，简要阐述加速等效试验的基本原理、方法、试验程序的编制及验证。

This paper takes the decelerator installed in the aeroengine(p=507 kW,n1 = 41 350r/min)as example,described briefly the basic principle, method,test programming of the Accelerated Misson Test and the verification.
