AERODYNAMIC PROFILE OF THE AIRCRAFT CARRIER Russian patent published in 2021 - IPC B64C27/467 B64C11/18 

FIELD: aircrafts.

SUBSTANCE: invention relates to the field of profiles of rotor blades of an aircraft. The aerodynamic profile of the aircraft carrier includes the upper and lower contours formed by convex curves and their points of intersection with given coordinates relative to the airfoil chord. The coordinates of convex curves are counted from the midline of the profile, while the upper coordinate is added and the lower one is subtracted, the coordinates are determined by the ratios of the coordinates of the points of the contours along the X axis to the length of the profile chord, the coordinates of the points of the midline along the Y axis to the length of the profile chord, the ratio of the coordinates of the points of the upper and the lower contours along the Y axis to the length of the profile chord, the parameter along the X axis is calculated using one formula, and the upper contour is calculated using another formula.

EFFECT: invention is aimed at improving the quality, more stable focus position when changing Mach numbers, and also allows you to get a higher maximum thrust with increased wind resistance.
