Analysis of service ceiling on piston aero-engine

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.
