MAIN LANDING GEAR WITH RIGID REAR LEG Russian patent published in 2014 - IPC B64C25/12 

FIELD: transport.

SUBSTANCE: main landing gear comprises elongated beam, damper, folding front leg and rigid rear leg. Said elongated beam is articulated with aircraft to turn about its lengthwise axis. Note here that beam rotational axis is parallel with fuselage lengthwise axis. One end of the damper is articulated with elongated beam while its opposite end is articulated with wheel unit. Folding front leg first end is articulated with elongated beam and second end articulated with damper. Rigid rear leg first end is articulated with aircraft and second end articulated with damper. Note here that rear led confines the damper path in displacement between released and retracted positions so that wheel unit is located at the front and nearby aircraft axis in retracted position as compared with its position in retracted state.

EFFECT: simple and reliable design, decreased weight.
