ALL-PURPOSE VEHICLE ON ROTARY SCREW PROPULSOR Russian patent published in 2019 - IPC B62D57/36 B60F3/00 B63H1/00 

FIELD: transportation.

SUBSTANCE: invention relates to design of vehicles on rotary screw propulsors. Universal vehicle with rotary screw propulsor comprises housing and rotor-screw propulsor. Rotor-screw propulsor consists of modules fixed on body of vehicle movable two from each side by means of three-point suspension. Each module of rotary screw propulsor consists of two semi-rotors installed coaxially with possibility of independent rotation in movable support frame, which is pivoted and controlled by hydraulic cylinders in vertical and horizontal planes. Every half-rotor is driven by built-in hydraulic motor.

EFFECT: enabling complete adaptability of rotary screw propeller to track surface, maximum contact of rotors with soil, minimization of housing roll during movement on a hilly slope, maintaining stable movement of the body along a given curvilinear trajectory and most complete implementation of traction capabilities for engagement of the propulsor with soil.
