Ws-9 Engine Test Performance Calculation And Analysis

In this paper, for the requirements of aeroengine testing and WS-9 aeroengine Computer Aided Testing(CAT) system, a steady-state numerical model of the WS-9 aeroengine is developed. It is discussed in detail that the structure of Q440, the WS-9 steady-state performance program. And it is clarified that the thermodynamic mumerical processes of the engine's parts. Firstly, the performance is calculated at the design point of the WS-9 aeroengine by using the numerical model established. Secondly, after obtaining the performance coupling parameters, the steady-state performance of the non-designed points is caculated. Third, respectively make the limitation of rotate speed of the high pressure rotor and low pressure rotor equal to corresponding parameters of designed point, after the data calculated compared with those of designed point and actual testing of the manufactory, the error is obtained. At the end, the significance of this paper is discussed at the aspects of guidance and evaluation o f the aeroengine testing in manufactory, and the developing of the aeroengine CAT system.
