The Development of a T53-L11 Engine Computer Model

Abstract

This Technical Memorandum describes the development of a steady-state engine model for a Lycoming T53 turboshaft engine. A genuine compressor map obtained from Lycoming was integrated into a generic gas turbine modelling program called Turbotrans. Both engine performance predictions and the variation of output power with free turbine speed showed good correlation with manufacturer's data. The ability to simulate engine wear and damage via degraded component efficiencies was demonstrated but not validated. Keywords: Australia; Gas turbine engines.
