When the aircraft is turning on the ground, environmental factors such as uneven airport pavement and sidewind may cause the actual angle of the steering wheel of the main landing gear to be inconsistent with the theoretical angle, resulting in the mismatch between the front wheel angle and the main wheel angle on both sides, increasing the tire lateral force and increasing the torque on the main landing gear. To solve the above problems, the ground turning control strategy with independent control of main wheels on both sides, the master-slave control strategy with steering wheel of inner main landing gear as the dominant object and steering wheel of outer main landing gear as the slave object, and the real-time cornering angle control algorithm were put forward. The total landing gear torque of an aircraft during ground cornering was calculated by establishing a ground cornering model based on elastic tires. Through setting different angle deviations of main wheels by MATLAB, the independent control strategy of main wheels on both sides and the total torque of main landing gear under master-slave control strategy were compared. It is found that the former can effectively reduce the torque of main landing gear, increase the safety of aircraft ground cornering and reduce the difficulty of landing gear design.
