A retractable landing gear for an amphibious aircraft

Abstract

The invention relates to a retractable landing gear of an amphibious aircraft. The retractable landing gear comprises a front landing gear retraction mechanism and a rear landing gear retraction mechanism, wherein front landing gear retraction mechanism comprises a front airplane wheel, a front supporting component, a front retraction jack and a front airplane wheel storage cabin; the front supporting component is arranged inside the front airplane wheel storage cabin and is simultaneously articulated with the front airplane wheel and the front retraction jack; the front retraction jack is used for driving the front airplane wheel to extend out of the front airplane storage cabin or retract to the front airplane storage cabin by the front supporting component; the rear landing gear retraction mechanism comprises a left airplane wheel, a right airplane wheel, a rear supporting component and a rear retraction jack; the rear supporting component is arranged inside the body and is simultaneously articulated with the left airplane wheel, the right airplane wheel and the rear retraction jack; the rear retraction jack is used for driving the left airplane wheel to extend out of or retract to a left pontoon and driving the right airplane wheel to extend out of or retract to a right pontoon by the rear supporting component. Compared with the prior art, the retractable landing gear disclosed by the invention has the advantages of being simple in structural installation, flexible in retraction, small in floor space, high in safety, high in stability and the like.

Description

technical field [0001] The invention relates to an aircraft landing gear, in particular to a retractable landing gear for an amphibious aircraft. Background technique [0002] At present, there are more and more studies on amphibious aircraft, and the hull-type seaplane is popular because of its small size, convenient operation and many other advantages. However, the landing gear of some hull-type seaplanes has a single function and is exposed outside the fuselage. Due to the exposed landing gear tires during water taxiing, it is easy to be caught by aquatic plants or rope obstacles, which seriously affects flight safety. At the same time, due to the exposure of the landing gear, the flight resistance increases. [0003] Chinese patent CN 211924819 U introduces a personal amphibious vehicle, which includes a body, a cockpit and a sheet body. A front landing gear and a front landing gear retractable device are arranged at the bottom of the front end of the sheet body. Equip...
