摘要: 通过对某航空活塞增压发动机仿真分析与实验研究,以使用高度上可调节范围作为该类发动机使用升限的一般标准,依据其工作过程和控制规律探讨了使用范围变化的内在原因,提出了与压气机、涡轮参数有关的方程.为提高动力性能,设计了匹配良好的二级增压系统,依据该标准仿真分析了其极限高度与使用升限的可调范围,并给出进一步的改进建议.

Abstract: A model created by GT-power which had been verificated by experiment was analysed to find the criterion which eventually was found associated with its available range.The general criterion of how to determine the service ceiling of piston aero-engine was proposed in theory.The internal causes about the criterion was found by analysing its work process and regularity of control.A equation was established about the parameter of compressor and turbo to determine the service ceiling of engine.To reach the motive force requirement of high altitude light aero-plane,a two-stage turbo charging system matching the engine well was designed for the engine.The available range and service ceiling of the two-stage turbo charging aero-engine were established by simulation and the criterion proposed.The suggestion of how to improve the new engine was gived.
