FIELD: transport; machine building.
SUBSTANCE: invention relates to transport engineering, in particular to off-road vehicles. Screw-type propulsor comprises a rotor with a screw flange provided with a rotation mechanism and a rotary head. Helical incomplete crest is multi-threaded in the form of helical toroid segments fixed at the corresponding level of the rods in a three-rod revolving turnstile device mounted on a hub lying in the plane of an inclined ellipse cross section of the circular cylinder. Ellipse major axis is inclined to circular cylinder cross-section at angle of 45°, and minor axis of ellipse is larger than that of circular cylinder.
EFFECT: it is possible to expand the functionality of the screw propulsion in wheelchairs for movement on hard surfaces with obstacles.
