中文摘要:
      本文提出了一种测量涡喷发动机过渡过程的专用仪器——涡喷发动机过渡工作线显示仪。它可以根据发动机进气的总压和静压以及出口的总压信号实时计算出发动机的瞬时换算空气流量及压气机增压比,因而将发动机的瞬时工作线自动显示出来。文章给出了仪器的原理,线路和性能。利用此仪器对发动机的各种过渡过程进行了分析研究。测定了发动机在加速、减速过程和失速喘振过程中工作点移动的轨迹,分析了其工作特征。
英文摘要:
      A special instument is presented for monitoring the transient process in a turbojet engine, which is called "transient operating line indicator". The instrument consists of analog computing circuits. It demonstrates the real-time flowrate and the pressure ratio of the engine which are calculated from the total pressure and the static pressure at the inlet and the total pressure at the exit of the compressor. By means of this instrument the transient operating line of the engine can be plotted with an x-y recorder. The description, the circuits and the performance of this instrument are given in this paper. The various transient processes of turbojet engine, such as acceleration, deceleration and surge, have been studied with this instrument.
