The invention belongs to the technical field of aero-engine control design, and particularly relates to a method for eliminating the idle stroke of an aero-engine throttle lever, which comprises the following steps of: determining the stroke range of a throttle lever in a slow running state, a throttling state and a specified thrust state; determining the rotating speed n1Rmc in a slow state under different heights H and Mach number Ma state points of the flight envelope; determining a required rotating speed n1R specification of a specified thrust state under different heights H and Mach number Ma state points of the flight envelope; on the basis of the state points of different heights H and Mach number Ma of a flight envelope, the rotating speed n1Rmc of a slow vehicle state and the required rotating speed n1R specification of a specified thrust state, the rotating speed n1R of a throttling state at different throttle lever angles PLA between the slow vehicle state and the specified thrust state is determined through interpolation.

    本申请属于航空发动机控制设计技术领域,具体涉及一种消除航空发动机油门杆空行程的方法,包括:确定慢车、节流以及规定推力状态油门杆的行程范围;确定飞行包线不同高度H及其马赫数Ma状态点下,慢车状态的转速n1Rmc;确定飞行包线不同高度H及其马赫数Ma状态点下,规定推力状态的需求转速n1R规定;基于飞行包线不同高度H及其马赫数Ma状态点下,慢车状态的转速n1Rmc、规定推力状态的需求转速n1R规定,插值确定慢车、规定推力状态间节流状态在不同油门杆角度PLA的转速n1R。
