圧縮機からの抽気によるターボジェットエンジン性能評価

抄録

It is well known that the bleeding of compressed air is a method to avoid unstable state such as surging in a compressor. The turbojet engine runs only at the point where each engine component satisfies matching conductions based on the matching theory. The change of engine performance by bleeding compressed air is estimated using the Performance Analysis Tool of Gas Turbine （GTPAT） based on matching theory. The air bleed holes have been provided at the compressor exit of a turbojet engine. In this paper, the performance of turbo jet engine has been estimated by using GTPAT, and the obtained results have been compared with the data obtained by experiments.
