The invention discloses a fixed-wing unmanned aerial vehicle catapult-assisted take-off device and a catapult-assisted take-off method, and belongs to the field of unmanned aerial vehicles. The fixed-wing unmanned aerial vehicle catapult-assisted take-off device comprises a catapult base, a base is slidably connected to the catapult base, and an elastic inhaul cable is connected between the base and the tail end of The top face of the base is provided with a fixed check block and a movable check block which are oppositely arranged in the head-tail direction. The movable stop block is connected to the base in a pivoted mode, and an elastic piece used for enabling the movable stop block to turn over to the position below the top face of the base is arranged between the movable stop block and the base. The movable check block is further fixedly connected with a rigid inhaul cable, a switch device is fixedly installed at the head end of the ejection base, and an action execution part of the switch device fixes and releases the rigid inhaul cable in a controlled mode. The locking device is simple in structure and more reasonable in design, an operator can synchronously lock the fixed-wing unmanned aerial vehicle to be catapulted while tensioning the elastic inhaul cable, operation is convenient, the situation that the operator forgets to lock the fixed-wing unmanned aerial vehicle to be catapulted is avoided, and safe and accident-free catapulting can be guaranteed.

    本发明公开了一种固定翼无人机弹射起飞装置及弹射起飞方法,属于无人机领域,包括弹射底座,弹射底座上滑动连接有基座,基座与弹射底座的尾端间连接有弹性拉索;基座的顶面设有沿首尾方向相对布置的固定挡块和活动挡块;活动挡块枢转连接在基座上,活动挡块与基座之间设有用于使活动挡块翻转至基座的顶面下方的弹性件;活动挡块还固定连接有刚性拉索,弹射底座的首端固定安装有开关装置,开关装置的动作执行部受控地固定及放开刚性拉索。本发明结构简单且设计更加合理,使操作人员能够在拉紧弹性拉索的同时同步地实现对待弹射的固定翼无人机的锁紧,不但操作方便,而且不会出现忘记锁紧待弹射的固定翼无人机的情况,从而能够保证安全无事故弹射。
