Abstract

The component-level mathematical model of a turbofan engine is established by the dynamic heat method, which is solved by N-R method. The throttle characteristics of the engine are simulated. The results show that as the engine rotating speed increases, the engine thrust gradually increases, and the sfc reduces at first and then rises, which are consistent with the actual work of the turbofan engine.
