Multifunctional tilting duct unmanned aerial vehicle

Abstract

The embodiment of the invention relates to a multifunctional tilting duct unmanned aerial vehicle which comprises a body. The body is integrally and rotatably connected with three ducts, and rotor wing groups for providing lift force are arranged in the ducts. Therefore, the problems in control, stability and safety of a traditional unmanned aerial vehicle can be solved. On the one hand, the multifunctional tilting duct unmanned aerial vehicle adopts a tiltable three-duct layout, the coaxial double rotors are arranged in the ducts, each duct can provide vector pulling force, thus the control flexibility of the aerial vehicle is improved, rapid conversion of the aerial vehicle between different flight modes is realized, and motion coupling of the aerial vehicle is effectively avoided. On the other hand, the ducts are nested in a spherical shell, the ducts are protected, and the freedom of the rotation of the ducts is increased. Meanwhile, a steering gear server is used for controlling tilting of the ducts, and the attitude change of the aircraft is enabled to be more diverse to meet the requirements 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.
