Abstract

The present study is aimed to develop an integrated performance analysis approach for the application of a compressor with variable inlet guide vane (VIGV) and vairable stator vane (VSV) in a small turbofan engine. For the integrated analysis approach, an engine performance analysis program, NPSS and a computer program used for predicting of axial flow compressor performance based on stage stacking method, STGSTK were linked with an optimisation package, Isight. This enables off-design performance analysis for the turbofan engine with VIGV and VSV hence provides the capability to predict stable operation condition of the engine with acceptable surge margin.

본 연구에서는 가변 안내익과 가변 정익을 가진 압축기가 적용된 소형 터보팬엔진의 통합성능해석법에 대한 연구를 수행하였다. 통합해석을 위해 Isight를 이용하여 엔진성능해석프로그램(NPSS)과 압축기탈 설계점 성능프로그램(STGSTK)을 연계하여 해석할 수 있는 절차 및 연계프로그램을 구축하였다. 각각의 해석프로그램은 실험데이터와 비교하여 타당성을 검증하였다. 이러한 통합 해석법을 적용한 결과 탈설계점에서 요구되는 서지마진을 가지는 가변시스템의 작동 조건을 예측할 수 있었다.
