Abstract

The invention relates to a three-section type fixed-wing unmanned aerial vehicle provided with a protection device. A wing of the fixed-wing unmanned aerial vehicle is of a three-section type wing-shaped structure and comprises a slat which is arranged at the front edge of the wing, a main wing which is arranged in the middle of the wing and a wing flap which is arranged at the rear edge of the wing; the main wing comprises a central wing and outer wings located at two sides of the central wing; the wing flap comprises a wing flap arranged at the rear edge of the central wing and secondary wing flaps arranged at the outer edges of the outer wings; a forward pull type screw propeller is arranged at the front end of a fuselage; a protection device comprises a screw propeller protection device, a wingtip protection device and an empennage protection device. The three-section type fixed-wing unmanned aerial vehicle provided by the invention has the advantages that the three-section type fixed-wing unmanned aerial vehicle has a higher lift coefficient and the aerial vehicle has higher maximum lift; meanwhile, the fuselage and the screw propeller can be reasonably protected.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a three-stage fixed-wing unmanned aerial vehicle provided with a protection device. Background technique [0002] In recent years, with the development of unmanned aerial vehicle technology and the reduction of cost, fixed-wing unmanned aerial vehicles have been widely used in various fields such as military, security, transportation, exploration, surveying and mapping, and meteorology. In the military field, fixed-wing UAVs are generally used for high-altitude and high-speed reconnaissance and strikes. In the civilian field, fixed-wing UAVs are generally used for aerial photography, surveying and mapping, and inspections. [0003] Various applications of drones have different technical requirements. For example, UAVs used for long-range reconnaissance have high requirements on the cruise of the aircraft, while UAVs that take off and land in the wild require that the air...
