用于随发动机健康变化的调制涡轮冷却的方法及系统
摘要：
提供一种调制涡轮冷却(MTC)控制系统(180)。MTC控制系统(180)包括与存储器(204)通信的处理器(202)。处理器(202)编程成针对多个操作条件中的各个确定发动机构件(128,130)的冷却流需求。处理器(202)还编程成在多个操作条件中的各个相应的操作条件期间将确定的所需流引导至发动机构件(128,130)。处理器(202)还编程成评估发动机构件(128,130)的健康，以及基于发动机构件(128,130)的评估的健康来修改确定的冷却流需求。处理器(202)还编程成在多个操作条件中的各个随后相应的操作条件期间将修改的冷却流需求供应至发动机构件(128,130)。
摘要（英）：

A modulated turbine cooling (MTC) control system (180) is provided. The MTC control system (180) includes a processor (202) in communication with a memory (204). The processor (202) is programmed to determine a cooling flow requirement of an engine component (128, 130) for each of a plurality of operating conditions. The processor (202) is further programmed to channel the determined required flow to the engine component (128, 130) during each respective operating condition of the plurality of operating conditions. The processor (202) is also programmed to assess a health of the engine component (128, 130), and modify the determined cooling flow requirement based on the assessed health of the engine component (128, 130). The processor (202) is further programmed to supply the modified cooling flow requirement to the engine component (128, 130) during each subsequent respective operating condition of the plurality of operating conditions.
