FIELD: mechanics.

SUBSTANCE: invention relates to auger/screw propellers for high-traffic vehicles. The screw propeller contains a hollow cylindrical rotor with a helical ridge and a rotation mechanism, as well as a swivel head. The helical comb is made in the form of a system of pneumatic wheels, the axes of rotation of which are mounted on the cylindrical surface of the rotor and are parallel to the axis of rotation of the cylindrical rotor. The group wheel rotation mechanism, which complements the main drive mechanism of the cylindrical rotor, is made in the form of a rotor filling the central part of the cylindrical rotor.
