Embodiment Construction

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only for illustration and are not intended to limit the present invention.

[0053] The invention proposes a miniature fixed-wing unmanned aerial vehicle whose belly absorbs the wall. The flying weight is about 250-600g. It can perform adsorption operations on various vertical walls. It can be used as a temporary monitoring point for reconnaissance in complex environments. Its structure includes a host Wing 1, vector power system 2, aerodynamic rudder surface 3, vertical tail 4, adsorption-detachment system 5 and belly equipment warehouse 6, such as figure 2 shown.

[0054] The interior of the belly is designed with a belly equipment compartment 6, the two sides of the belly are connected to the main wing 1, and the mounting s...

Abstract

The invention discloses a miniature fixed-wing unmanned aerial vehicle with a belly adsorbed on a wall surface, which comprises a main wing, a vector power system, a pneumatic control surface, a vertical fin, an adsorption-separation system and a belly equipment bin, wherein the adsorption-separation system is mounted on the middle upper side of the belly; the adsorption-separation system comprises bionic adsorption dry glue and a separation servo mechanism; the bionic adsorption dry glue is laid on the outer side of the belly in the front-back direction of the main wing and is used for adsorbing a wall surface; two sets of separation servo mechanisms are symmetrically mounted on two sides of the belly and are used for realizing separation of the bionic adsorption dry glue from the wall surface; and the separation servo mechanism comprises a wall separation servo steering engine, a wall separation cam and a wall separation rocker arm. After the unmanned aerial vehicle flies to a preset site for a long distance, low-power-consumption long-time adsorption on a vertical wall surface can be realized, a reconnaissance task can be executed in the adsorption process, and the unmanned aerial vehicle is separated from the wall surface and returns after being completed.

Description

technical field [0001] The invention relates to the technical field of miniature unmanned aerial vehicles, in particular to a miniature fixed-wing unmanned aerial vehicle whose belly absorbs the wall. Background technique [0002] At present, large-scale drones have been used more and more in actual combat, but they still cannot play a role in anti-terrorism operations, specific area reconnaissance, target person tracking, and indoor covert reconnaissance. Supplement the existing military UAV equipment system. Micro UAVs refer to aircrafts that are only the size of a palm (about 15cm). According to their flight principles, they can be divided into three configurations: fixed-wing micro-aircraft, rotary-wing micro-aircraft and flapping-wing micro-aircraft. Since the 1990s, micro-UAVs have attracted the attention of various countries, and countries around the world represented by the United States have carried out research on them. Among them, fixed-wing UAVs have high effici...
