摘要
对于飞机滑跑时的操纵前轮转弯运动，本文建立了包括飞机整体运动和前轮转向运动的数学模型，用牛顿－欧拉法导出了非线性运动微分方程组，并求出数值解。在一定限制条件下计算出飞机前轮的最大转向角和飞机的动态响应曲线及其重心的运动轨迹。
For the aircraft maneuvering turn by steering nose wheel in taxiing, a methematical model describing both the whole aircraft motion and nose wheel steering is established in this paper. A set of nonlinear differential equtions of the motion are derived by NewtonEuler method and solved numerically by RungeKutta method. The maximum steering angular of nose wheel is calculated under the given conditions, and the aircraft response curves and the trajectory of the centre of gravity are drawn during the aircraft turning by the maximum steering angular of nose wheel. The turn region area calculated is compared with that of the simplified theory.
