AEROCAR Russian patent published in 2020 - IPC B60F5/02 B64C29/00 

FIELD: aviation.

SUBSTANCE: invention relates to air transport. Aerocar comprises housing, engine, vertical lift propellers arranged along the left and right sides of the hull, cruise propellers connected to engine via toothed infinitely variable variator, control mechanisms. Each of disks of vertical and vertical lifts of upper and lower groups is made of two interchangeable disks – upper and lower ones, bolted to each other by their end surfaces. On upper end surface of upper disc and lower end surface of lower disc there are pointed radial teeth narrowing to center of rotation and expanding from center of rotation. Teeth on upper disc are deflected in opposite direction from direction of rotation, and teeth on lower disc are deflected in direction of rotation. Outer surface of each tooth is shaped to a convex hyperbolic curve, the initial point of which lies on the end surface of the disc, and the inner surface of each tooth is concave and represents a part of the circumference connecting the tooth apex and the end surface of the disc.

EFFECT: higher operational characteristics of the aerocar, higher lifting force of vertical lift propellers and higher carrying capacity.
