An aircraft auxiliary driving system and method for asymmetric thrust compensation in approach phase

Abstract

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 .

Description

technical field [0001] The invention relates to a method for assisting piloting of an aircraft, more specifically, a method for assisting the pilot in identifying the failed engine and compensating for the asymmetrical yaw moment after a single-engine failure occurs in the approach phase of a twin-engine aircraft and asymmetrical thrust is generated. , a system and method for providing autonomous approach landing or go-around control when necessary. Background technique [0002] When a multi-engine aircraft is in flight, if a single engine or a single engine fails, the vertical and horizontal heading balance of the aircraft will be destroyed, resulting in a large asymmetric yaw moment, causing the aircraft to deflect and tilt sharply. If the asymmetric thrust is not compensated in time, the sideslip angle will continue to increase, which will lead to the deterioration of the lift-drag characteristics of the aircraft, and in severe cases, the aircraft will stall. In the appr...

Problems solved by technology

It can be seen that the pilot's control burden and decision-making pressure are huge, but the time left for the pilot is relatively short. Affected by factors such as flying skills, ability to deal with sudden abnormal phenomena, and psychological quality, the pilot is likely to experience improper control or Mishandling, leading to flight accidents
