FLYING VEHICLE COMPARTMENT Russian patent published in 2003 - IPC

FIELD: aeronautical engineering. SUBSTANCE: compartment of seaplane hull for example includes front and rear main frames, skin strengthened by stringers and standard frames, nose-wheel well, entry door located on ports side of seaplane hull, loading hatch located on starboard side and bulkhead separating the crew cabin from technical compartment. Nose-wheel well is bounded lengthwise by front and rear main frames which are simultaneously front and rear walls which transmit load from nose undercarriage leg to seaplane hull sides. Front main frame is also used as watertight bulkhead separating crew cabin from technical compartment. Beam of front main frame is just front load-bearing rim of loading hatch aperture shaping strip and front load-bearing rim of entry door aperture; beam of rear main frame is rear load-bearing rim of loading hatch aperture shaping strip. EFFECT: simplified construction; reduced mass. 4 dwg
