VEHICLE WITH THREE COMPOSITE WINGS Russian patent published in 2022 - IPC B64C39/06 B64C39/08 B64D27/12 B64C5/02 B64C3/40 

FIELD: vehicles.

SUBSTANCE: vehicle for air, water, land, or space vehicles contains a fuselage, front, center, and rear composite wings. Front composite wings have a sweep and a positive transverse V, first inclined planes (2), the first elevators, the first ailerons, and first means (3) of increasing lift force, and they are made with the possibility of connection to central and rear composite wings. Central composite wings are made with second inclined planes (12), the second ailerons, second means of increasing lift force (4), and wingtips (5). Rear wings are located in upper and rear positions relatively to the fuselage and rudder (7) of the vehicle in the forward and downward direction. Each of front wings, central wings, and rear wings is equipped with power plant (1, 6, 11). Central composite wings are located in the upper part of the fuselage, and the transverse V changes so that it is positive, zero, or negative. The change is carried out in a fixed manner in a vehicle structure or before the vehicle is operated. Rear wings are connected in the outer part to front composite wings and central composite wings. Rear composite wings are swept with a negative transverse V, have two third elevators, the third ailerons, two third inclined planes (8), third means of increasing lift force (9), and are connected by rudder (7) to the fuselage.

EFFECT: invention is aimed at reduction in inductive resistance and interference resistance, provision of greater maneuverability, increase in the maximum speed, and reduction in the minimum speed.
