A miniature fixed-wing UAV that can be adsorbed on a plane

Abstract

The invention discloses a miniature fixed-wing unmanned aerial vehicle that can be adsorbed on a plane. It is mainly a miniature fixed-wing unmanned aerial vehicle that can be adsorbed on the wall by relying on bionic gecko nano-adsorption materials. , the main wing adopts a rectangular wing, with a typical wingspan of 150‑350mm and a typical length of 150‑300mm. The power system is arranged at the leading edge of the wing, and the motor mounting frame increases the height of the motor to avoid interference between the propeller and the wall. Arrange the biomimetic gecko nano-absorbent material and the servo mechanism for detaching from the wall. The UAV of the present invention can realize the process of hovering, level flight and working condition conversion. After being converted to vertical flight mode, facing the wall, the process of wall adsorption can be realized, and then the propeller can be turned off for reconnaissance. After completing the task, The plane can be detached from the wall by a servo system, and then converted to level flight mode.

Description

technical field [0001] The invention belongs to the technical field of micro unmanned aerial vehicles, and specifically designs a miniature fixed-wing unmanned aerial vehicle that can be adsorbed on a plane, and can be used for reconnaissance and strike tasks on complex battlefields. Background technique [0002] Recently, with the continuous expansion of UAV market demand and the continuous development of UAV technology, the miniaturization of UAV has become one of the important development directions in this field. Micro Air Vehicle (MAV) is a category of drones. The flying speed of a micro air vehicle is about 5-20m / s, and the maximum design length of its fuselage is between 10-15cm, which is about the palm of an adult. size aircraft. Later, with the development of technology and in-depth research on actual usage, the size restrictions on micro air vehicles were gradually relaxed, and more functions and practicability of drones were pursued. MAVs are mainly divided into...

AI Technical Summary

Problems solved by technology

Among them, the magnetic adsorption can only work on the magnetically conductive surface, and the generated adsorption force is strong, but the noise is also relatively large

Negative pressure adsorption relies on the vacuum pump to absorb the gas in the suction cup to achieve adsorption, which requires high smoothness of the wall, and has high noise and power consumption

Thrust adsorption relies on its own propulsion device to generate gas away from the wall surface, which has strong adaptability to the wall surface, but the device generating thrust is large in size and low in efficiency, and the noise is also obvious
