ENGINE NACELLE ON AIRCRAFT WING Russian patent published in 2017 - IPC B64D27/02 

FIELD: machine building.

SUBSTANCE: invention relates to aeronautical engineering. Nacelle (1) on the wing (3) of the aircraft is set so that the coordinate on X axis is 0.7÷0.8 of a mean aerodynamic wing chord, laid from the leading edge (6) to the nacelle nozzle edge (5), on Y axis is 0.01÷0.1 of a mean aerodynamic wing chord obtained as a perpendicular from the bottom surface of the nacelle to the wing plane (6), the angle of the nacelle installation in a vertical plane laid from the nacelle midline (9) to a construction horizontal (7) of the fuselage (4) is 6÷8°, the nacelle contour lower surface (8) is of non-rectilinear shape with a negative camber.

EFFECT: invention reduces noise by shielding effect of the airframe and improves fuel efficiency values.
