The invention discloses a fixed-wing unmanned aerial vehicle capable of taking off and landing on snow. The fixed-wing unmanned aerial vehicle comprises a vehicle body, an engine is detachably installed at the top end of the vehicle body, a rotor wing is rotatably connected to one end of the engine, an empennage is fixedly installed on one side of the vehicle body, a steel plate is installed in the vehicle body in an embedded mode, and a front undercarriage and a main undercarriage are sequentially installed at the bottom end of the vehicle body from left to right. Sledges are detachably mounted at the bottom ends of the main undercarriage and the front undercarriage. By arranging the movable plate and the electric telescopic rod, the electric telescopic rod is used for driving the movableplate to be screwed out of the front end of the vehicle body, and the protection effect of the movable plate is used, so that snow piles are prevented from directly impacting precise parts in the vehicle body, then safety of the parts in the vehicle body is guaranteed, and the practicability of the device is improved; and meanwhile, the protective steel plate at the bottom end of the vehicle bodyis utilized, so that abrasion is small when parts in the vehicle body have flight accidents, and then the cost of single flight of the unmanned aerial vehicle is reduced.

    本发明公开了一种可雪上起降的固定翼无人机,包括机身,机身的顶端可拆卸安装有发动机,发动机的一端转动连接有旋翼,机身的一侧固定安装有尾翼,机身的内部镶嵌安装有钢板,机身的底端从左到右依次安装有前起落架和主起落架,主起落架和前起落架的底端均可拆卸安装有雪橇。本发明通过设置了活动板和电动伸缩杆,利用了电动伸缩杆带动活动板在机身前端进行旋出,利用了活动板的防护效果,避免了雪堆直接冲击到机身内部的精密部件,进而保证了机身内部零件的安全,增加了该装置的实用性,同时利用了机身底端的防护钢板,使得机身内部零件发生飞行意外时,磨损较小,进而降低了无人机单次飞行的成本。
