FLYING VEHICLE-CONVERTIPLANE-AMPHIBIAN (VERSIONS) Russian patent published in 2007 - IPC B64C39/08 B64C37/00 B60F5/02 B64C29/02 

FIELD: aviation; manufacture of manned and unmanned vertical takeoff and landing convertible flying vehicles.

SUBSTANCE: according to first version, proposed flying vehicle has star-shaped wings which are spaced apart in each crossing vertical planes at even number of rays. Mounted on tips of wings in engine nacelles are power plants forming rigid structure in each crossing plane. Wings are provided with adaptive control surfaces for activation of them according to required modes of operation of power plants and counteraction to external disturbing factors in accordance with objective synergetic laws of unity of adaptation and control processes. Lower parts of engine nacelles have extension displacement-type alighting gears of changeable volume for retraction into internal cavities of engine nacelles. According to second version, flying vehicle is provided with even number of detachable aerodynamic wings of optimal aspect ratio. Their outer panels are secured on fuselage in between planes of star-shaped wings, thus forming different aerodynamic configurations. According to third version, each power plant of flying vehicle is provided with at least two coaxially independent drives with air screws in thrust ring. Each alighting gear may be made in form of folding corrugated cylinder and sphere. Interior of this cylinder is divided into two cavities by elastic transversal partition fitted with reducer valve. Envelope of sphere may be retracted into end cavity of cylinder. Its end face is provided with swivel tabs of fairing. Alighting gears may be provided with splittable doors with inflated ballonets secured in their cavities.

EFFECT: enhanced efficiency of flying vehicle especially at turbulence of atmosphere; high rate of climbing; reduction of power requirements of power plants; enhanced maneuverability; wide range of change of flying speed, hovering inclusive.
