Abstract

The effect of component deterioration on engine performance is considerable. This influence can not be easily computed with normal engine steady performance computer program. A new mathematical method and computer program were developed to accurately compute the effect of component deterioration on engine performance. First, the mechanisms of the effect of component deterioration on engine performance were analyzed; then, statistical method was used to calculate this influence. Taking a turbofan engine as an example, the effect of component deterioration on engine performance, such as specific fuel consumption and temperature at turbine inlet was computed with this method, and compared with experimental data. The results indicate that the mathematical model in this paper can be used to compute the effect of component deterioration on engine performance.
