AIRCRAFT RETRACTABLE LANDING GEAR Russian patent published in 2015 - IPC B64C25/10 B64C25/12 

FIELD: transport.

SUBSTANCE: invention relates to a landing gear of an aircraft (A) and concerns a retractable landing gear. The retractable landing gear of the aircraft contains a stationary leg fastened to a hull, a depreciation leg, a cart with a wheel pair, a hinged connection, a lever spatial mechanism locking the mechanisms fixing positions of links in respect to stationary and mobile legs. The lever mechanism is capable to adopt the flat position - preset in motion by the engine. The lever spatial mechanism is designed comprising of six links which are connected to each other by hinges forming only rotary kinematic pairs. Four links are implemented in the form of rods with identical parameters, with identical distances between axes of the hinges and identical angles of crossing equal to 90° and connected to each other in series with a possibility of overlapping of points of the ends of the shortest distances between the axes of the hinges of the first and second links. Meanwhile one of the links is implemented as the driving one and is connected only to a single engine.

EFFECT: improvement of the reliability and operability of the retractable landing gear is achieved.
