Single-duct coaxial reversal type double-rotor aircraft based on controllable deflector

Abstract

The invention discloses a single-duct coaxial reversal type double-rotor aircraft based on a controllable deflector. The aircraft is composed of an annular duct enclosure, a support, a coaxial reversal propeller, a fairing, the deflector and an electric and control system. The annular duct enclosure is transparent and internally hollow, and is internally provided with a multi-directional slot formounting a sensor, a steering engine and other electronic equipment. The duct enclosure eliminates the flying safety threat caused by exposure of a traditional structure rotor, and improves the working efficiency of the rotor; a stretchable support is arranged under the duct enclosure, and the support is automatically laid down during landing, so that safe landing is realized; coaxial reversal type double rotors are matched with the fairing and a butterfly-shaped body, vertical lifting of an aircraft body can be realized, and the inertial autorotation of the aircraft body is not required to becounteracted by additional arranging a tail rotor; and the non-vertical movement of the aircraft in the air is realized through the cooperation of the deflectable deflector below the double rotors, the control system controls a motor according to data of the sensor, so that autonomous or artificial flight control on the aircraft is realized

Description

technical field [0001] The invention relates to aircraft design, especially a single-duct vertically liftable unmanned aerial vehicle. Background technique [0002] In recent years, with the development of aerodynamics and the progress of material science, small aircraft, especially unmanned aerial vehicles, have achieved unprecedented development. A traditional small electric helicopter consists of a single rotor and a tail rotor. In addition, coaxial anti-propeller electric helicopters and multi-rotor UAVs are also emerging in large numbers. [0003] However, in terms of mechanical structure, many aircraft, especially UAVs, have the problem of rotor exposure. Although many drones have a protective frame on the outside of the rotor, it is still impossible to completely avoid collisions in flight, and additional air resistance and air interference will be greatly increased during flight, which will easily lead to its own crash and endanger the surrounding area.

Problems solved by technology

Although this simplifies the balance control, it limits the number of external equipment and the installation location, and also increases the danger when the drone lands.

From the perspective of intelligence, most of the current aircraft and drones are controlled by human remote control, the degree of intelligence is very low, and few have intelligent capabilities such as autonomous cruise and autonomous wind resistance mode change.
