Method for determining component matching and operating characteristics for turbojet engines

Maps a r e developed f o r matching the compressor and turbine components of a singlespool engine.Component pressure ratios and engine temperature ratios a r e determined which satisfy the matching requirements of flow, power, and rotative speed.The method of development is primarily graphic in form.Operating lines a r e constructed which illustrate two modes of engine operation for two types of missions.Transient operation is also considered.Included is the effect of varying the nozzle throat a r e a on matching the components.
