AIRCRAFT "SHOTA" WITH SPECIAL PROPELLER Russian patent published in 1994 - IPC

FIELD: aviation. SUBSTANCE: aircraft has apparatus, that ensures its steadiness in flight, suspended loading compartment, controlled in plane of symmetry of flying aircraft, special air propellers with changeable in flight step, changeable diameter and twisting form of blades. Apparatus to ensure aircraft steadiness in flight is placed in lower part of body of aircraft and is made in the form of rail, bent on arc of circumference with center of curvature located close to center of mass of aircraft, and is provided with rollers and braking means, engaged with rail and load compartment, made as changeable suspended container. Blades of special air propeller are made of inner and outer parts, that are telescopically connected to each other and are capable for mutual longitudinal movement in guides. Besides, blades are provided with means of turning and changing of twisting by commands from system of control. During change of power plant operation modes and terms of flight, system of control is capable to send signals to change diameter of propellers, to change step and twisting of blades and so increase of power plant efficiency is achieved. Movement of load compartment mass along arc of circumference allows to control position of aircraft in vertical plane of its symmetry. EFFECT: aircraft "SHOTA" is used in aviation. 6 cl, 17 dwg
