The invention provides an unmanned aerial vehicle sliding anti-crosswind capability assessment method. The method comprises the following steps: obtaining pneumatic data in a sliding process of an unmanned aerial vehicle; determining an evaluated skating speed feature point range; according to the taxiing speed feature point range, taxiing speed feature points are selected, and the evaluated roll angle rate range and yaw angle rate range are determined; according to the determined airspeed range, the roll angle rate range and the yaw angle rate range, the maximum sideslip angle and the maximum crosswind value which can be balanced when the rudder reaches the maximum value within the value range of the taxiing speed feature points are solved. According to the method, the motion mode is simplified, the section prone to lateral deviation is selected for analysis, and modeling of the complex skating motion process is avoided.
本发明提供一种无人机滑跑抗侧风能力评估方法,包括以下步骤:获取无人机滑行过程中的气动数据;确定评估的滑跑速度特征点范围;根据滑跑速度特征点范围,选取滑跑速度特征点,确定评估的滚转角速率范围和偏航角速率范围;根据确定的空速范围、滚转角速率范围和偏航角速率范围,求解在滑跑速度特征点取值范围内,方向舵达到最大值能够平衡的最大侧滑角和侧风值。本发明对运动模态进行简化,选择较易发生侧偏段进行分析,避免了对滑跑复杂运动过程的建模。
