AERODYNAMIC SURFACE AND AIRFRAME OF AIRCRAFT Russian patent published in 2018 - IPC B64C3/28 B64C23/06 B64C31/02 

FIELD: physics; aviation.

SUBSTANCE: group of inventions refers to the field of aerodynamics. Aerodynamic surface is made with an aerodynamic profile and comprises a front and a back edge, an upper and a lower side, as well as generators of vortices. Leading edge is formed by a sequence of protrusions and troughs with a cyclically varying local sweep angle. Vortex generators are made in the form of leading edge sections with the greatest local sweep angles. Aerodynamic surface additionally contains ridges. Protrusions of the leading edge are made in the form of teeth having a wedge-shaped or leaf-like shape. Cavities of the leading edge are made in the form of intermediate zones. Ridges are oriented in the direction of the air flow and are arranged in pairs on the upper and lower sides of the aerodynamic surface in close proximity to the inwardly directed fractures of the leading edge. Airframe of the aircraft contains a fuselage, landing gear, wing and horizontal tail, which are made in the form of said aerodynamic surface.

EFFECT: group of inventions is aimed at improving flight safety by simplifying piloting.
