LANDING GEAR COMPARTMENT OF REDUCED OVERALL DIMENSIONS Russian patent published in 2012 - IPC B64C1/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, more particularly, to landing gear compartment and aircraft containing such landing gear compartment. Landing gear compartment includes caisson (16) of longitudinal mode containing walls which determine inner niche (24) opened from bottom to allow landing gear (20) to be retracted into the niche and released from the niche. Caisson walls separate inner unsealed niche from surrounding sealed area (18) of aircraft. The caisson contains primary inner frame including several inner primary transversal caisson reinforcement arcs (26, 28), inner relative to niche longitudinal central reinforcement member (30a, 30b); herewith, walls and reinforcement members are shaped so that they can follow shapes of landing gear (20) and its retraction/release actuator (22).

EFFECT: decrease in overall dimensions of aircraft landing gear.
