| 摘 要： | 本文研究了用Kane方程来建立包括起落架机构的弹性飞机系统动力方程的方法。给出了跑道表面的两种计算模型。然后,讨论了弹性飞机在起飞和着陆过程中的姿态、速度、加速度和动载荷的数字模拟方法,计及起落架诸大构件的惯性力和惯性力矩对飞机系统运动的影响。作为一个简单的例子,本文模拟了KC-135飞机的对称起飞和着陆。

| Abstract: | The method of using Kane's equation to develop the dynamic equations of a flexible aircraft system including landing gear mechanisms is investigated in this paper. Two kinds of mathematical models of runway surface are given. Then, the numerical simulation method is discussed for simulating the attitude, velocities, accelerations and dynamic loads of a flexible aircraft during take-off and landing, taktng into accounf of the effect of inertial forces and moments of large landing gear parts on the motion of the system. As a simple example, the symmetric take-off and landing of KC-135 aircraft on the runway No. 12 is simulated. The numerical results are only for reference. |
