| 摘 要： | 针对某燃气涡轮性能试验台，选择空气流量、燃油流量、水流量以及涡轮背压作为控制系统的主要控制量。通过建立工作点附近的线性“小偏差”方程，讨论了以上四种因素对于涡轮的入口压强、入口温度和转速这三个状态变量的影响程度。压强主要取决于空气流量．温度对空气和燃油均有一定的敏感性，转速则主要由水流量来控制。基于以上判断确定了试验台的手动调节规律。

| Abstract: | This paper introduced a gas turbine performance test bench of a liquid rocket engine. The mass fluxes of air, fuel, water and outlet pressure of the gas turbine were chosen to be the main controlling elements in the system. The dynamical model of every part was established. The effective elements on inlet pressure, inlet temperature and rotating speed of the gas turbine are analyzed by using linear small deviation equations. The regulating rule of manual control was confirmed. The inlet pressure of the gas turbine depended on the air flux. The inlet temperature related with both air flux and fuel flux. The rotating speed was controlled by the water flux. |
