METHOD OF LIFTING TO STARTING POSITION OF FLEX-WING OF AIRCRAFT Russian patent published in 2024 - IPC B64C3/30 

FIELD: aircraft engineering.

SUBSTANCE: invention can be used in method of lifting flex-wing to launch position in structures of parachutes, kites and aircrafts (AC) with flex-wing. Method of lifting to the starting position of the flex-wing of an aircraft, with an air propeller creating an air flow, made with a gas-tight pneumatic frame, filled from a compressed gas source through a flexible gas line and through a relief valve releasing the pneumatic frame of the wing from gas, with the flex-wing lifting vertically above the moved object, with tension by a system of slings secured on a movable object, when a pneumatic frame of a flex-wing is filled with gas. Air is pumped into the gas-tight pneumatic frame of the wing, and the airborne wing is lifted to the starting position by the air flow perpendicular to the ground and the plane of the flex-wing, passing through at least one or more holes, made in flex-wing created in each of holes during rotation of propeller of air propeller mounted on electric motor shaft, when electric power is supplied to electric motor, via electric cable from electric power source fixed on movable object.

EFFECT: claimed invention is aimed at creation of a method of wing lifting to a launching position, without application of lifting static Archimedean force regardless of presence of external air flow, as well as collection and storage of flex-wing of aircraft in small volume in assembled form and low cost with improved functional properties.
