Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft structural design technology, specifically to a landing gear protective baffle that is easy to install. Background Technology
[0002] Aircraft are used to transport personnel and cargo, and for firefighting and disaster relief. They often operate in arid, humid, and even Arctic regions. These areas often have poor geological conditions, with few or no airports or suitable runways. Therefore, aircraft sometimes land on unpaved runways, such as dry soil, clay, or even gravel runways. These unstable runway surfaces contain many small debris particles that can be splashed up when the aircraft's nose landing gear tires drive over them at high speed, threatening the radar radome and antennas mounted on the aircraft's belly. Therefore, landing gear protective fenders are necessary for protection.
[0003] According to Chinese Patent Publication No. CN207417131U, a landing gear protective baffle includes a protective baffle and a connecting bracket. The protective baffle features a hyperboloid design on the side near the nose landing gear tire, which deflects small debris splashed up by the aircraft tire to the outside of the wheel through a guiding mechanism. Even if small debris bounces back after hitting the ground, it will not impact the aircraft's underbelly equipment. Furthermore, the connecting bracket positions the protective baffle directly behind the nose landing gear tire, completely blocking small debris splashed up by the tire. While this technology achieves the protective effect, it is inconvenient to install, requiring multiple bolts and reducing installation efficiency. Therefore, a landing gear protective baffle that is easier to install is proposed to solve the aforementioned problems. Utility Model Content
