Anti-foreign body device installed on aircraft landing gear

Abstract

A foreign matter prevention device mounted on an airplane landing gear is characterized in that a baffle is extruded on a strut of the airplane landing gear through a rubber bushing, the rubber bushing consists of two semi-circle bushings, and as rubber has a relatively high friction coefficient, the baffle is fixed on the strut of the airplane landing gear through a frictional force produced by extruding the rubber bushing. The baffle consists of two semi-circle baffles between which a gap is reserved. The positive pole and the negative pole of a power grid are alternately arranged and mounted on the inner side of the baffle. A capacitor and a switch are fixedly mounted on the outer side of the baffle. The positive pole and the negative pole of the power grid are connected in series withthe capacitor and the switch. A touched foreign matter is electrically shocked by a relatively high current produced during discharge of the capacitor. As the positive pole and the negative pole of the power grid are densely and alternately arranged, and the two poles of the capacitor have relatively high voltages, when the foreign matter touches the positive pole and the negative pole of the foreign matter, discharge of the capacitor is promoted to prevent the foreign matter from crossing the baffle. The foreign matter prevention device is high in practicability, easy to popularize and relatively high in value.

Description

technical field [0001] The invention relates to the technical field of aircraft structures, in particular to an anti-foreign object device installed on an aircraft landing gear. Background technique [0002] When the aircraft is parked on the ground, foreign objects such as rats, snakes, and insects will occasionally climb into the aircraft. As more and more sophisticated electronic devices are installed on the aircraft, if the foreign objects enter and bite the cables or remain in the body, it will cause serious accidents. very serious consequences. At present, more and more attention is paid to the anti-foreign object measures used when the aircraft stays on the ground. However, the anti-foreign object measures adopted are mainly protective baffles, which simply enclose the aircraft, and only increase the height of the baffle to increase the protective effect. This tends to cause the protective baffle to be too large, and it is inconvenient to carry and install, and the c...

Problems solved by technology

At present, more and more attention is paid to the anti-foreign object measures used when the aircraft stays on the ground. However, the anti-foreign object measures adopted are mainly protective baffles, which simply enclose the aircraft, and only increase the height of the baffle to increase the protective effect. This will easily lead to too large protective baffles, inconvenient handling and installation, and high cost. At the same time, it does not have a good protective effect on animals that can crawl on vertical surfaces such as insects.
