AERODYNAMIC AIRCRAFT Russian patent published in 2017 - IPC B60V1/14 

FIELD: transportation.

SUBSTANCE: aerodynamic aircraft comprises a body, the main engine, mechanically connected to vertical lift propellers, a main propulsion system, mechanically connected to sustainer propulsion devices, two conical double differentials joined to mechanisms of aircraft control in the space and vertical lift propellers, air-and-water steering wheels. Each vertical lift propeller comprises a cylindrical body with a gear in the middle part, driven shafts of which are installed vertically, with fixed upper and lower disc groups. Upper surface of each propeller disc is made as wavy in the form of radial spherical cavities and bulges alternating between each other, and on the lower surface there are dead depressions opening towards the lower surface of the disc in the form of truncated triangles, as well as "Л"-shaped internal radial channels made in the form of isosceles triangles, having inlet and outlet windows on the lower surface of the disc.

EFFECT: increased life force of vertical lift propellers.
