Abstract

Abstract:

A strategy for fully automatic asymmetrical thrust compensation for multi-engine aircraft is researched. The lateral-directional balanced conditions for the asymmetrical thrust flight are derived. An automatic compensation control method is proposed based on speed signals of the engine rotor. The method proposed not only ensures good compensation purpose, but also obviously increases reliability of the automatic compensation system. Logic operation of high pressure and low pressure rotor speed signals are conducted, and the differential high pressure rotor speed between symmetrical engines is used to modify the aileron and rudder response commands. The asymmetrical thrust flight is then compensated with the method proposed together with the primary flight control system. The automatic compensation control system is optimized based on the characteristic that lateral-directional primary flight control possesses roll angle hold function. A linear mathematical model for aircraft balanced conditions are developed for full envelop. Control law for fully automatic compensation of the asymmetrical thrust flight is obtained. Six degree of freedom aircraft nonlinear equations are modeled and simulated by MATLAB/Simulink. The simulation result shows that the method proposed can be used to achieve excellent compensation of asymmetrical thrust flight.

Key words: asymmetrical thrust, automatic compensation, failure of engine, lateral-directional control, high pressure rotor, low pressure rotor
