AI Technical Summary
The existing turbofan engine's thrust-throttle lever angle relationship is designed to be non-linear, resulting in excessively sensitive or sluggish thrust response in certain throttle ranges. This increases pilot workload, fuel consumption, and potential flight risks, affecting flight experience and combat effectiveness.
By obtaining the relationship curves between the engine's low-pressure speed and thrust, and throttle lever angle, a linearization requirement curve for the throttle lever angle and thrust is formulated. Based on this, the nozzle area and low-pressure speed are adjusted to establish the relationship between low-pressure speed and throttle lever angle, thereby achieving linearized control of thrust and throttle lever angle.
It improves the linearity of thrust and throttle lever angle, reduces the pilot's workload, reduces fuel consumption, and enhances flight safety and combat effectiveness.
