A multifunctional tilting duct unmanned aerial vehicle

Abstract

The embodiment of the present invention relates to a multifunctional tilting duct unmanned aerial vehicle, comprising: a body, the body is integrally rotatably connected with three ducts, and a rotor set for providing lift is arranged in the ducts. Thus, the problems of traditional unmanned aerial vehicles in terms of control, stability and safety can be solved. On the one hand, the present invention adopts the layout of three tiltable ducts, and the ducts are coaxial dual-rotors, and each duct can Provides vector pulling force, thereby improving the maneuverability of the aircraft, realizing the rapid conversion of the aircraft between different flight modes, and effectively avoiding the kinematic coupling of the aircraft; on the other hand, nesting the duct in the spherical shell, both The duct is protected, and the freedom of duct rotation is increased. At the same time, the steering gear servo is used to control the tilt of the duct, so that the attitude of the aircraft can be changed more diversely to meet the needs of different environments and different tasks.

Description

technical field [0001] Embodiments of the present invention relate to the field of unmanned aerial vehicles, in particular to a multifunctional tilting duct unmanned aerial vehicle. Background technique [0002] With the development of the general aviation industry, unmanned aerial vehicles will be widely used in military and civilian fields. Among all kinds of aircraft, rotorcraft has developed rapidly due to its excellent take-off and landing performance and hovering performance, but ordinary aircraft have large noise, serious coupling, and poor safety. Although single-duct and double-duct aircraft are small in size and flexible in manipulation, they are effective. The load is small, which limits its application. The four-duct aircraft has a large payload, but there is little room for further development. It is not as flexible as the three-duct aircraft and has a lagging response. Generally, the tilt rotor adopts shaft rotation, and the high-speed rotating blades are easy...

AI Technical Summary

Problems solved by technology

Among all kinds of aircraft, rotorcraft has developed rapidly due to its excellent take-off and landing performance and hovering performance, but ordinary aircraft have large noise, serious coupling, and poor safety. Although single-duct and double-duct aircraft are small in size and flexible in manipulation, they are effective. The load is small, which limits its application. The payload of the four-channel aircraft is large, but the space for further development is small. It is not as flexible as the three-channel aircraft and there is a phenomenon of lag in response.

Generally, the tilt rotor adopts shaft rotation, and the high-speed rotating blades are easy to touch the duct wall, which reduces the safety.
