Three-section type fixed-wing unmanned aerial vehicle provided with protection device

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...

AI Technical Summary

Problems solved by technology

The front-pull fixed-wing UAV is the most vulnerable to damage because its propeller is located at the front, and it is also dangerous to the people around it, other animals and plants

Especially the existing unmanned aerial vehicles, the maximum lift coefficient is not enough, can not meet the requirements of use well
