发动机飞行载荷可靠性分析

ENGINE FLIGHT LOAD RELIABILITY ANALYSIS

本文在大量飞行试验实际测量数据和相当数量外场使用数据上 ,进行较为全面统计分析 ,运用可靠性理论分析美军用标准发动机通用规范 ( MIL- E- 50 0 7D)和发动机结构完整性大纲( MIL - STD- 1783)有关设计任务论述 ,对用 2倍设计任务进行发动机低循环疲劳寿命计算和试验要求 ,作了理论性探讨 ,并为某发动机飞行试验实测数据的统计分析所证实。

Engine Flight L oad Reliability Analysis”is a special reliablity re- search on the subject of engine integral load chart based on“JX/TJ(Trubojet) X Engine Flight Load Mesurement”.This paper makes full scale statistics and analysis on a greatnum- ber of data obtained form the actual measurements of flighttesting and quite a number of da- ta collected from flight- line service.Atheorticalresearch has been made on application of dou- ble design works to engine low cycle fatigue life calculation and testing.The results of this research have been proved by the statistics and analysis of JX/TJX Engine Flying Testing Measurements
