【Abstract】 Based on a conventional turbofan steady performance mathematical model, and combined withthe working principle of the lifting system, steady performance mathematical model of a turbofan enginewith the shaft-driven lift-fan was built with thrust ratio as a control target. According to this model, steadyperformance simulation software was compiled and calculation analysis was carried out on three typicalworking conditions. The calculation findings suggest that the procedure of the software is logically accurate,and the precision of the calculation will satisfy the further research. It provides the foundation for the perfor-mance analysis and control law design of shaft-driven lift-fan turbofan.更多还原
