无人机滑跑起飞过程及其数学模型研究

无人机地面滑跑起飞时的运动特性与空中飞行时的有所不同。以某型无人机为背景，描述了无人机地面滑跑起飞的全过程，分析了无人机在滑跑起飞各个阶段的受力情况，并逐一建立了各个阶段的运动方程（数学模型），在飞机地面运动模型中采用了弹性的轮胎和起落架模型。仿真结果表明，建立的模型比较准确地反映该无人机地面滑跑起飞的运动特性。

Process and Mathematic Model Study of a UAV during Taxing and Takeoff

During taxiing and takeoff UAV has unique dynamical characteristics different from that of flight, as regards a certain type of domestic UAV, the whole process of a UAV during taxiing and takeoff is described, the strength pressed on the UAV in every stages are analysed, and the motion equation during each stage are established. In the ground motion model, the elastomeric model of tires and landing gears is applied. The simulation result proves that the model almost accurately represents the actual dynamical characteristics of the UAV during taxiing and takeoff.
