The invention discloses a centroid-variable airbag buffer landing method for a small flying-wing unmanned aerial vehicle, the advantage of large wing area of the flying-wing unmanned aerial vehicle isfully utilized, and in the free falling process, a wing surface forms a resistance surface, so that the vertical falling speed of the unmanned aerial vehicle can be effectively reduced; compared witha parachute, the resistance characteristic is small, the falling speed is moderate, and the problem that the falling speed is low and drifts along with wind is solved; through gradual deceleration inthree stages of deep stall deceleration, vertical descending airfoil resistance deceleration and grounding airbag deceleration, the deceleration load is reduced, and the integrity of the unmanned aerial vehicle body and the load is effectively ensured.
本发明公开了一种小型飞翼无人机变质心气囊缓冲降落方法,充分利用了飞翼无人机自身翼面积大的优点,在自由下落过程中,翼面自身即构成阻力面,可以有效减缓无人机竖直下落的速度;同时,相对于降落伞,其阻力特征较小,下落速度适中,避免了下落速度慢随风飘移的问题;通过深度失速减速、竖直下降翼面阻力减速和触地气囊减速三个阶段逐次减速,降低了减速载荷,有效保证了无人机机体和载荷的完整。
