摘要
为优化涡扇发动机的持久试车谱,减少试验过程中的三红线构型改装次数,对持久试车谱的等效设计与符合性验证方法进行研究.分析了持久原始试车谱及其不同阶段的损伤特征,以发动机零部件的等效损伤为原则,以减少三红线构型改装次数为目的,提出一种基于等效损伤原则的等效持久试车谱适航符合性设计与验证方法,并以某型发动机高压涡轮叶片为例提出模拟特征试验件设计方案.所提方法可作为整机持久适航取证试验试车谱优化工作的参考,所提方案可支撑模拟特征试验件的等效损伤试验.
Abstract
In order to optimize the endurance test cycle of the turbofan engine and reduce the number of triple red-line configuration modifications during the test,the equivalent design and compliance verification method of the endurance test cycle were studied.The damage characteristics of the original endurance test cycle and endurance test cycle at different stages were analyzed,and a design and verification method for the airworthiness compliance of the equivalent endurance test cycle based on the principle of equivalent damage was proposed to reduce the number of triple red-line configuration modifications.A simulated characteristic test piece was designed by taking the high-pressure turbine blade of a certain engine as an example.The proposed design and verification method for the airworthiness compliance of the equivalent endurance test cycle of a turbofan engine can be used as a reference for the optimization of the test cycle of the endurance airworthiness certification test of the whole engine,and the proposed design scheme of the simulated characteristic test piece can support the equivalent damage test of the simulated characteristic test piece.
