ACTIVE SEMI-LEVERED LANDING GEAR Russian patent published in 2018 - IPC B64C25/22 B64C25/34 B64C25/50 B64C25/60 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to an active semi-levered chassis for use in an aircraft and concerns the increase in the height of the aircraft above the ground during the take-off phase. Active semi-levered chassis comprises a main strut, the main struck comprising a main strut oleo-pneumatic chamber, having a chamber pressure and a main strut piston, as well as the pressure boost mechanism. Pressure boosting mechanism comprises a first fluid portion having a pressure of a first portion of the fluid, and a second fluid portion having a second portion of the fluid pressure, the first portion of the fluid being selectively connected to the main strut oleo-pneumatic chamber. In this case, increasing the pressure of the second portion of the fluid increases the pressure of the first portion of the fluid. Pressure increase of the first fluid portion increases the chamber pressure to increase the length of the main strut piston to the extended length to provide an elongated main strut and the increased altitude of the aircraft above the ground during the take-off phase of the flight.

EFFECT: increase in the length of the main pillar and the height of the aircraft above the ground during take-off is achieved.
