摘要

摘要: In order to make the power level angle (PLA) have the same bijection relationship with the thrust when the environment changes before operational limit exceedance, and ensure the pilots ability of unrestricted throttle movement as well as the safety of the engine, a method used to design a constant thrust power schedule was proposed. The research was based on a simulink turbofan engine model and the results were organized as look-up tables in different structures with limitations. Simulation was done to confirm the validity and demonstrate the effectiveness of the schedule obtained with the approach. The constant thrust takeoff schedule, constant thrust idle schedule and constant thrust part power schedule with the present constant thrust control (CTC) method were proved to be valid. The results can be applied to this specific engine but the method can be applied to any areoengine and can be even extended to the unmanned plane.
