提出了基于高压涡轮(HPT)叶片寿命损耗计算的功率控制策略.通过飞机和发动机模型在不同环境条件下进行飞行任务仿真,得到推力需求及HPT叶片温度等参数,采用逆向工程方法进行HPT叶片寿命损耗计算.结果表明:在满足推力需求的同时,采用降低HPT叶片温度的控制策略能明显减少在不同环境条件下HPT叶片寿命损耗.通过不断调整发动机高压涡轮环境温度使之工作在推力需求基线附近,达到了有效延长发动机寿命的目的,验证了高压涡轮叶片寿命损耗计算方法简单可行.表明基于HPT叶片寿命损耗的发动机功率控制降低发动机寿命周期成本的有效性.
Proposed a power control strategy based on HPT blade life loss calculation.Airplane and engine models were used to simulate the flight mission under different environmental conditions and get thrust requirements and HPT blade temperature and other parameters, reverse engineering method for HPT blade life The results show that, while satisfying the thrust demand, the control strategy of reducing the HPT blade temperature can obviously reduce the life loss of HPT blades under different environmental conditions, by constantly adjusting the engine high pressure turbine ambient temperature to work near the thrust demand baseline , Which can effectively extend the life of the engine and verify that the calculation method of life loss of high pressure turbine blade is simple and feasible.It shows that the engine power control based on HPT blade life loss can reduce the life cycle cost of the engine.
