Problems solved by technology

[0002] The traditional airdrop device is mainly a parachute. Its principle is to use air resistance to slow down the falling speed so that the load can land safely. Highly demanding tasks; second, the landing speed is insufficient and the device is large in size, which is easy to be detected and is not suitable for concealed tasks; third, it has poor wind resistance and is greatly restricted by environmental factors; the flying snake has excellent gliding ability, When falling from a high place, by shaking the ribs, the body twists, swings and relaxes continuously. From an aerodynamic point of view, this makes them suitable for gliding; if the existing airdrop device is combined with the gliding characteristics of the flying snake , making full use of the principles of bionics to improve the existing airdrop device will greatly improve the performance of the existing airdrop device

Abstract

The invention discloses a novel gliding type bionic air-drop device, comprising a box body, four sets of stretching mechanisms, flexible wing cloth, a stretching driving mechanism, a lateral turning connecting rod, a stretching motor, lateral turning driving mechanisms, lateral turning motors, sensors, a gyroscope and a posture controller as well as a support plate group; the stretching mechanism has a semi-circular frame structure and contains a link mechanism, the stretching mechanisms are respectively arranged at two sides of the box body symmetrically, and the flexible wing cloth is fixed on the stretching mechanism; a support plate is arranged in the box body to be used for holding the stretching driving mechanism and the stretching motor; the lateral turning driving mechanisms, the lateral turning motors and the sensors are symmetrically arranged at two sides of the box body; and the gyroscope and the posture controller are fixed at the bottom center of the box body. According to the invention, the sensors and the gyroscope are used for sampling environment and posture parameters, so that the movement of the stretching mechanisms and the wing cloth can be controlled in real time, and the gliding posture of the air-drop device can be adjusted in real time, and therefore, the air-drop device can precisely and quickly reach a target area.
