Vectored thrust type unmanned aerial vehicle

Abstract

The invention relates to a vectored thrust type unmanned aerial vehicle. The vehicle comprises propellers, a body, wings and empennages, wherein the propellers are coaxially mounted at the front end of a longitudinal shaft of the body; the wings are symmetrically mounted on two sides of the middle part of the body; the empennages are symmetrically mounted on two sides of the tail part of the body; a vectored thrust device is mounted at the tail part of the longitudinal shaft of the body, and comprises a motor and a spray pipe; the motor is mounted inside the body; and the front end of the spray pipe is connected with the motor, and the tail end of the spray pipe extends outside the tail end of the body. The vehicle has the advantages of scientific design, reasonable structure, strong controllability, quick taking-off and landing speed, good safety, small size, light weight and good maneuvering characteristic, can guarantee low-speed maneuvering flight in a state of high attack angle, can effectively improve the maneuverability, and can shorten the skating distance in the taking-off and landing process.

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 magnitude and direction quantity. 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 UAVs is relatively small. In this state, the wings and tails of UAVs can generate enough lift to ensure the normal flight of UAVs. However, when the angle of attack of the drone gradually increases, the tail of the drone will fall into the low-energy wake of the wing, which may cause the tail to stall, or even cause the drone to enter a tail spin and cause a crash. At this time, even if the motor works Normal, also can't get the drone to balance and stay in the air. [0004] After searching, the following related...

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
