MATHEMATICAL MODELLING AND PERFORMANCE EVALUATION OF THE CM14 TURBOJET ENGINE

Abstract

ABSTRACT

This work focuses on evaluating the performance of a laboratory model CM14 turbojet engine through finding and analyzing the engine performance parameters. An integrated mathematical model was developed for the CM14 turbojet engine by deriving the detailed equations for the different engine components. The derived engine model will help in studying the engine performance at different operating conditions without performing heavily expensive experiments. Simulations for the derived model were carried out using MATLAB and Simulink. To ensure the reliability of the derived model the obtained results from the simulation were compared with an experimental data from the real CM14 turbojet engine at maximum rpm. The comparison shows that the obtained performance parameters from the derived model are reasonable and satisfactory.
