The invention discloses an aircraft auxiliary driving
system and method for asymmetric thrust compensation in the approach phase. The
system includes an asymmetric thrust identification subsystem (100), an auxiliary level decision-making subsystem (200), and an auxiliary compensation control subsystem (300), an
autonomous control subsystem (400), and a control coordination
system (500). After a single engine failure occurs in a twin-engine aircraft, the lateral balance of the aircraft is destroyed, and the
yaw moment and sideslip angle continue to increase. If it occurs during the approach phase that is closer to the ground, the
pilot needs to make quick decisions and restore a stable approach state, otherwise there will be a risk of crashing. The invention monitors the state of the engine in real time through the asymmetrical thrust identification subsystem (100). If a single engine failure occurs, the auxiliary level decision-making subsystem (200) is started, and the auxiliary mode for the
pilot is given according to the information of the man-
machine environment. Through the auxiliary compensation control subsystem (300) or the
autonomous control subsystem (400), the
rudder surface deflection command is automatically calculated, and input into the aircraft through the control coordination system (500), assisting the
pilot to complete the approach and landing task, effectively ensuring
flight safety .
