AIRPLANE AND METHOD OF ITS CONVERSION IN PARKING POSITION Russian patent published in 1994 - IPC

FIELD: aviation. SUBSTANCE: airplane has fuselage with cabin, powerplant composed of engine and puller propeller, tricycle landing gear with nose and main landing gear units and conventional tail unit. Structural members of fuselage consist of four planar frames, lower load-bearing platform, four load-bearing beams, frame and fuselage pipe. The load-bearing beams are rigidly coupled with the fuselage pipe, and with corners of frame and aft planar frame. Airplane wings are turnable in their hinge fittings and foldable afterwards along airplane centerline. The load-bearing platform has fittings for attachment of springs of the main LG units in both airplane configurations, with tail and nose LG units. Point of attachment of strut to wing span lies within the limits of 0.3-0.4 wing half-span. Parking position of the airplane is attained by turning the wings till they are oriented along the airplane centerline. EFFECT: simpler design, smaller weight, better controllability, wider scope of vision from cockpit, higher versatility of landing gear. 10 cl, 5 dwg
