AERODYNAMIC FUSELAGE OF THE AIRCRAFT Russian patent published in 2018 - IPC B64C1/38 B64C21/02 

FIELD: aviation.

SUBSTANCE: aerodynamic fuselage of the aircraft contains the front, main and tail sections. In cross section, the main part of the fuselage is made with a width exceeding the height, which gradually decreases towards the tail part. First aerodynamic device that is rigidly fixed to the upper surface and the second aerodynamic device that is rigidly fixed to the lower surface of the main body of the fuselage are provided. First aerodynamic device comprises a box-shaped quadrangular housing with an upper wall made with through holes, with a through slot-like cavity, in the longitudinal section increasing towards the tail of the fuselage, and a partition located longitudinally in the through slot-like cavity. Area of the flow cross-section of the outlet of the through slot-like cavity is equal to or larger than the sum of the areas of the flow cross-section of the inlet and the flow cross-sections of all through-holes made on the upper wall of the box quadrangular housing. Second aerodynamic device comprises a box-shaped quadrangular housing with a rear wall, a bottom wall made with through holes, a slot-like cavity and partitions longitudinally located in the slot-like cavity. Area of the flow cross-section of the inlet of the through slot-like cavity is equal to or less than the areas of the flow cross-sections of all through holes made in the bottom wall of the box-like housing.

EFFECT: invention is aimed at increasing the efficiency of creating an uplift by the fuselage of the aircraft by providing an increase in pressure below the lower surface of the fuselage.
