A miniature vertical takeoff and landing flapping wing aircraft

Abstract

The invention discloses a miniature vertical take-off and landing flapping-wing aircraft, and belongs to the technical field of flapping-wing aircrafts. The aircraft comprises an aircraft body, a flight control system, a steering engine, a double-wing flapping wing device and a tail vane. The double-wing flapping wing device is arranged at the upper part of the aircraft body, and the tail vane isarranged at the lower part of the aircraft body. The double-wing flapping wing device comprises a flapping wing driving part and a flapping wing synchronous movement mechanism which are mounted on a rack. The flapping wing driving part comprises a motor and a reduction gear set, the motor is in meshed connection with an input end gear of the reduction gear set through a motor shaft gear arranged on a rotating shaft of the motor, and the flapping wing synchronous movement mechanism comprises a flapping wing and a pair of flapping wing driving structures of the same structure. The flapping wingcomprises a flapping wing rocker arm and two pairs of flexible flapping wings. The flapping wing driving structure comprises an eccentric shaft mounting gear, an eccentric shaft and a connecting rod.The cross-shaped supporting tail vane comprises a longitudinal fixed rudder plate and a transverse adjusting rudder plate, and the longitudinal fixed rudder plate and the transverse adjusting rudder plate are vertically downward and are arranged in a cross mode. The aircraft has the characteristics of convenient take-off and landing, low energy consumption and the like.

Description

technical field [0001] The invention relates to the technical field of flapping-wing aircraft. Background technique [0002] The bionic flight of flapping-wing aircraft has broad application prospects in national defense and military affairs. When the flapping-wing aircraft is flying, the energy it carries is limited, which requires it to save energy as much as possible in the process of performing tasks. , it is required to hide in a certain corner for fixed-point monitoring, and then take off again to perform the next task after the monitoring is completed), so the aircraft is required to complete landing or take-off actions at any time and place to deal with random situations, and this action is It needs to be completed without human intervention or indirect intervention, so it is required that the flapping wing aircraft must have the ability to take off and land autonomously with a small amount of energy consumption.

Problems solved by technology

[0003] Chinese Patent Publication No.: CN108557074A, publication date September 21, 2018, the title of the invention is a flapping-wing aircraft with a three-rotor hybrid layout and a control method. The application discloses a layout form combining a three-rotor and a flexible flapping wing. It aims to solve the problem that the existing flapping-wing aircraft cannot take into account both vertical take-off and landing and fast level flight. The aerodynamic coupling problem between the rotor and the flapping wing system is also difficult to solve

Chinese Patent Publication No.: CN108363408A, publication date January 26, 2018, the title of the invention is a flapping-wing aircraft autonomous take-off control system and method, the application discloses a method of using a remote control car to load the flapping-wing aircraft to take off. The most important thing is that the device can only be used once, and it is essentially the same as hand-throwing

When the flapping-wing aircraft lands directly on the ground during fixed-point investigation, it will greatly limit its detection field of vision. For example, the "homing pigeon" bionic detection flapping wing system developed by Northwestern Polytechnical University in China has a camera installed on the abdomen of the flapping wing. If it lands directly on the ground, the reconnaissance mission cannot be continued. In view of this problem, the team proposed a solution using bionic landing gear. The bionic landing gear system and landing control method, the imitation bird claw structure proposed by the invention can make the flapping wing aircraft perch on the wires and branches, and its deficiency is to add a set of corresponding drive system to increase the mechanical bird claw device. At the same time, the take-off weight of the flapping wing aircraft is increased, and its payload is reduced

For the fixed-point perch of the flapping wing aircraft, it involves the research field of perch and perch robots. In addition to the bionic landing gear structure mentioned above, there are also methods such as magnetic adsorption and vacuum adsorption. However, in combination with practical applications, these methods are all There are many deficiencies, so the bionic perch of the flapping wing aircraft is still a difficult problem to solve
