Abstract

A mathematical model was introduced for the calculation of component material warm-up effect on centrifugal compressor efficiency during turboshaft engine starting.According to the turboshaft engine’s starting fuel flow

starting characteristics was calculated and compared with the engine test data to verify the accuracy of the model.Then

the model was used to analyze component material warm-up effect on the turboshaft engine starting characteristics.
