Flapping wing-flapping rotor wing multi-flight-mode bionic aircraft

Abstract

The invention discloses a flapping wing-flapping rotor wing multi-flight-mode bionic aircraft which comprises a rack, and a motor is arranged on the rack; the output end of the motor is connected with a crank sliding block mechanism through a first-stage reduction gear set and a second-stage reduction gear set. A center rod connected with the crank sliding block mechanism is arranged on the rack in a penetrating manner, and the center rod is rotationally connected with a wing frame through a first rotating bearing; the center rod is sleeved with a rod sleeve connected to the rack, and the rod sleeve is connected with a supporting base through a second rotating bearing. Fork hands are hinged to the two sides of the supporting base respectively. Lower driving back plates are hinged to the two sides of the wing frame correspondingly, and the middles of the lower driving back plates are hinged to the upper gaps of the forks; a steering engine assembly is arranged at the upper end of the lower driving back plate and connected with an upper driving back plate, and a sleeve pin device is arranged on the upper driving back plate and connected with wings. According to the invention, the aircraft has the high-maneuverability vertical take-off and landing performance of the flapping rotor wing and the efficient cruise flight performance similar to the flapping wing.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a flapping wing-flapping rotor multi-flight mode bionic aircraft. Background technique [0002] For a long time, humans have carried out a large number of detailed observations and researches on the flapping of flying biological wings (especially insect wings), and found that they can generate higher aerodynamic lift coefficients and have multiple flight modes - flapping forward flight, Wing gliding, vertical take-off and landing, hovering, etc. Inspired by birds flapping their wings for better flight ability, the flapping rotor combines flapping motion and rotating motion to obtain higher agility and flight efficiency. This concept was first proposed by Li Daochun, Wu Jianghao and others, and made a miniature Flyable experiments and aerodynamic analysis were carried out on the flapping rotor model. The flapping rotor not only has the ability of the rotor to take off verticall...

Problems solved by technology

At present, most flapping-wing aircraft at home and abroad are bird-like aircraft with flapping wings up and down. It is difficult for such bird-like aircraft to switch modes, thereby improving flexibility and better environmental adaptability
