The hybrid VTOL UAV system is a high-performance oil electric UAV system developed for use scenarios such as patrol and surveillance applications in aeronautics and light vehicles. The drone uses carbon fiber composite material to process the body, with a maximum take-off weight of 20kg. The UAV adopts a large aspect ratio wing design, and uses a large lift-to-drag ratio and excellent aerodynamic performance to match the wing body fusion layout. The high-performance aerodynamic design makes the UAV possess excellent flight performance. The rear wing adopts an inverted V tail layout that shares the structure with the vertical take-off and landing support rod; the fuselage is designed with three equipment compartments, which can be customized by users to meet the different needs of different users. This model adopts a tool-less disassembly design for the whole machine, which can be quickly installed and disassembled by a single person in three minutes. The hanging power system is equipped with an active propeller stopping mechanism, which keeps the hanging propeller at a low resistance position in the fixed-wing flight state, and also avoids damage to the power propeller during the operation of the UAV.
