Vector thrust type unmanned aerial vehicle

Abstract

The invention relates to a vector thrust type unmanned aerial vehicle. The vector thrust type unmanned aerial vehicle comprises a propeller, an aircraft body, wings and empennages; the propeller is coaxially mounted at the front end of the longitudinal axis of the aircraft body; the wings are symmetrically mounted on two sides of the middle of the aircraft body; the empennages are symmetrically mounted on two sides of the tail of the aircraft body; a vector thrust device is mounted at the tail of the longitudinal axis of the aircraft body and comprises a motor and a spray pipe; the motor is mounted inside the aircraft body; the front end of the spray pipe is connected with the motor; and the tail end of the spray pipe extends out of the tail end of the aircraft body. The vector thrust typeunmanned aerial vehicle is scientific in design, reasonable in structure, high in controllability, high in takeoff and landing speed, good in safety, capable of guaranteeing maneuvering flight undera low-speed and large-attack-angle state, small in size, light in weight and good in maneuvering performance; and the maneuverability of the unmanned aerial vehicle is effectively improved; the sliding distance of the unmanned aerial vehicle in a takeoff and landing processes can be shortened.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, in particular to a vector thrust type unmanned aerial vehicle. Background technique [0002] The thrust acting on the UAV is a quantity with magnitude and direction. This quantity is called a vector. Thrust vector technology is a technology that obtains additional steering torque by deflecting the direction of the motor jet. [0003] At present, the flight angle of attack of ordinary drones is relatively small. In this state, the wings and tail of the drone can generate enough lift to ensure the normal flight of the drone. However, when the drone’s angle of attack gradually increases, the tail of the drone will fall into the low-energy wake of the wing, which may cause the tail to stall, and even cause the drone to enter a tail spin and cause a crash. At this time, even if the motor is working Normal, also unable to keep the drone balanced and stay in the air. [0004] After searching, t...
