RETRACTABLE LANDING GEAR FOR FLYING VEHICLE Russian patent published in 2005 - IPC

FIELD: aeronautical engineering; landing gears of flying vehicles.

SUBSTANCE: proposed retractable landing gear has lever with wheel articulated on fuselage, gas-and-hydraulic shock absorber 3 with extension-retraction hydraulic cylinder 4. Shock absorber body 5 is articulated with lever and its rod is articulated with fuselage of flying vehicle. Rod of shock absorber 3 is mounted in body 5 by means of fixed axles boxes 7 and 8 forming gas chamber "A" and hydraulic chamber "B". Rod is stepped in construction: 6.1 is stage of larger diameter and 6.2 is stage of smaller diameter. Circular chamber formed between body 5, rod and fixed axle boxes 7, 8 is used for circular piston 9 mounted on rod stage 6.2 of smaller diameter which is movable and engageable with end face of rod of stage 6.1 of larger diameter. Circular piston 9 divides circular cavity into two chambers: air chamber "E" at atmospheric pressure and hydraulic chamber "D" connected with hydraulic system of flying vehicle.

EFFECT: extended functional capabilities.
