燃气涡轮发动机压缩机管理系统
摘要：
公开一种用于燃气涡轮发动机（10）的燃气涡轮发动机压缩机操作系统。所述燃气涡轮发动机（10）包括低压压缩机（14）和高压压缩机（15）。所述低压和高压压缩机（14、15）分别由低压和高压轴（26、27）驱动，其中所述高压压缩机（15）提供在所述低压压缩机（14）的核心质量流的下游。所述压缩机操作系统包括配置成控制所述低压压缩机（14）的可变几何形状致动器（32、34）的控制器（42）。所述控制器（42）配置成基于低压压缩机（14）转速（N1）和高压压缩机操作参数来控制所述可变几何形状致动器（32、34），所述高压压缩机操作参数例如核心质量流率（）、高压压缩机压力比（P30:P26）、高压压缩机转速（N2）和高压压缩机可变导向叶片角度（α）中的一者或多者。
摘要（英）：

A gas turbine engine compressor operating system for a gas turbine engine (10) is disclosed. The gas turbine engine (10) comprises a low pressure compressor (14) and a high pressure compressor (15). The low and high pressure compressors (14, 15) are driven by low and high pressure shafts (26, 27) respectively, with the high pressure compressor (15) being provided downstream in core mass flow of the low pressure compressor (14). The compressor operating system comprises a controller (42) configured to control a variable geometry actuator (32, 34) of the low pressure compressor (14). The controller (42) is configured to control the variable geometry actuator (32, 34) on the basis of low pressure compressor (14) rotational speed (N1) and a high pressure compressor operating parameter such asone or more of core mass flow rate (m), high pressure compressor pressure ratio (P30:P26), high pressure compressor rotational speed (N2), and high pressure compressor variable guide vane angle (alpha).
