An Investigation into Performance Modelling of a Small Gas Turbine Engine

Abstract

A small gas turbine performance modelling and testing project has been completed as part of a Divisional Enabling Research Program (DERP). The main objective of the program was to enhance DSTO's capability in understanding and modelling the thermodynamic and performance characteristics of gas turbine engines. Secondary objectives of the program included the investigation of thrust augmentation technologies and infrared suppression modelling and analysis. This report presents the results of both numerical and experimental investigation into engine performance simulation. It outlines the different tools and techniques used in modeling engine component behaviour and discusses their advantages and disadvantages. The results of two different tests designed to explore engine operating regions close to compressor stall and surge is presented.
