FIELD: engine building.
SUBSTANCE: invention relates to screw propulsor device. Screw propulsion unit comprises a hollow cylindrical rotor with a helical ridge, equipped with a rotation mechanism, and a swivel head. Rotary heads are made in the form of elastic soft pads fixed on caterpillar-type endless belt, which working branch is passed through cylindrical rotor cavity. At that, both branches of endless belt can be passed through cavity of cylindrical rotor.
EFFECT: it is possible to expand the functionality of the screw propulsion when moving on hard surfaces.
