摘要： An on/off surge prevention control and method for a gas turbine engine having a variable geometry diffuser is provided. This control receives exhaust gas temperature and compressor discharge pressure signals from the engine, and a signal from the aircraft indicative of a need for bleed air. When the aircraft signal is received, the control opens the diffuser to its maximum open setting, and when said aircraft signal is absent closes said diffuser to its minimum open setting. In the event that a faulty aircraft signal is received, the control senses changes in EGT, P3 and dP3/dt and compares these parameters to preselected values indicative of the compressor nearing surge. When the measured values reach the preselected values, the control closes the diffuser to it minimum open setting. By using a temperature signal in determining when to close the diffuser, unwanted closings due to operating transients in compressor discharge pressure are provided. The control prevents the diffuser from being opened, until a second preselected EGT is reached. This second EGT is selected so that it cannot be reached by the engine so long as said aircraft signal is false.

摘要： A modulating surge prevention control and method for a gas turbine engine having a variable geometry diffuser is provided. The control calculates a maximum permissible compressor discharge pressure from a predetermined algorithim that is representative of the compressor discharge pressure when the compressor is operating at its minimum permissible surge margin with the diffuser in its maximum open position. The control also receives a signal from a sensor measuring the actual compressor discharge pressure. A error signal is formed by taking the difference between the measured pressure signal and the calculated signal. The control then continously adjusts the area of the diffuser so as to maintain the actual compressor discharge pressure at or below the calculated pressure. The calculated pressure is also corrected for variations in ambient temperature and altitude.
摘要翻译：提供了具有可变几何形状扩散器的用于燃气涡轮发动机的调节浪涌预防控制和方法。该控制从压缩机以其最大允许喘振裕度运行时的压缩机排放压力的预定算法计算最大允许压缩机排出压力，其中扩散器处于其最大打开位置。该控制器还从传感器接收测量实际压缩机排气压力的信号。通过取测量压力信号与计算出的信号之差来形成误差信号。控制器然后连续地调节扩散器的面积，以将实际的压缩机排气压力保持在所计算的压力以下。计算的压力也会根据环境温度和高度的变化进行校正。
