SCREW MOTOR Russian patent published in 2018 - IPC B62D57/24 A61G5/06 

FIELD: machine building.

SUBSTANCE: invention relates to automotive industry. Screw propeller contains a rotor with a screw crest, between the crests of which is mounted pneumatic chamber. Rotor is made of a composite combined claw-like, where each component of the rotor is two claw-like counter-oriented rotors, shifted in angular relation to each other by half the distance between the claws in one of the rotors, between which the pneumatic chamber is mounted, and the claws of the rotor by the peripheral part form a multi-threaded helical crest. Each two claw-like counter-oriented rotors have a mechanism of axial displacement and fixation relative to each other, and each pneumatic chamber has a device for filling the chamber with air and/or gas and bleeding air and/or gas from the chamber.

EFFECT: increase in the propulsion of the propeller is achieved.
