[0043] Aircraft ground turn and its related parameters, such as Figure 1-2As shown, 1 is the side lines of the airport runway on both sides, 2 is the turning path of the left tire of the main landing gear of the aircraft, 3 is the position of the front landing gear tire before the aircraft turns around, 4 is the position of the aircraft before the turn, 5 is the position of the main landing gear tire before the aircraft turns around, 6 is the turning path of the front landing gear tire of the aircraft, 7 is the turning path of the right tire of the main landing gear of the aircraft, 8 is the position of the aircraft after the turn, 9 is the position of the main landing gear tire after the aircraft turns around, 10 is the position of the front landing gear tire after the aircraft turns around, 11 is the axis of the parallel symmetry plane of the front landing gear tire of the aircraft, and 12 is The complementary angle of the front wheel turning angle of the aircraft, 13 is the position of the central axis of the front landing gear tire of the aircraft perpendicular to the aircraft symmetry plane after being rotated according to the front wheel turning angle, 14 is the distance reserve Δ between the outer edge of the aircraft tire and the edge of the runway, 15 is the main wheel track a of the aircraft, 16 is the width S of the ground turn runway for the aircraft, 17 is the front wheel turning angle α of the aircraft, 18 is the position of the axis of the front landing gear tire of the aircraft parallel to the symmetry plane after being rotated according to the front wheel turning angle, 19 is the distance b between the front wheel and the main wheel of the aircraft, and 20 is the central axis of the main landing gear tire of the aircraft perpendicular to the symmetry plane.

[0044] When the aircraft turns on the ground, it moves in a nearly circular motion on the airport runway. When the front wheel of the aircraft turns at an angle of α, the center axis of the front landing gear tire of the aircraft perpendicular to the aircraft's symmetry plane will also rotate at the front wheel turning angle α. After the front landing gear tire of the aircraft rotates perpendicular to the center axis of the aircraft's symmetry plane, the intersection with the center axis of the main landing gear tire of the aircraft perpendicular to the symmetry plane is the center of the aircraft's turn. The aircraft rotates with this intersection as the center of the circle, and completes the turn after turning 180°. The distance between the outermost side of the main landing gear tire before and after the aircraft turns plus the distance allowance Δ from the outer edge of the tire to the edge of the runway is the ground turn runway width of the aircraft, which is the minimum safe width of the runway required for the aircraft to turn.
