Abstract


Virtual power extraction method (VPEM) of designing starting control law of turbofan engine was presented, and the computer program was developed. The VPEM of designing starting control law is based on the principle of VPEM of designing acceleration control law of turbofan engine, and combined with the method of extrapolation of component maps. The starting control law of some turbofan engine at single flight state and in whole starting envelope was designed by using the program, some computing results were analyzed. Computing results showed that VPEM is accurate and effective for designing starting control law of turbofan engine.
