FIELD: transportation.
SUBSTANCE: invention relates to transport engineering, in particular to off-road vehicles. Screw propeller contains a hollow rotor with a screw ridge. Hollow rotor is made of aluminum pipe or stainless steel pipe, round in cross-section, with longitudinal fins stripes with a pitch that divides 360°. Multiple screw ridge is assembled on a pipe made from a system of rubber and/or plastic sheets with mounting holes commensurate with the cross section of the pipe-finning assembly.
EFFECT: it is possible to expand the functionality of the screw propulsion in wheelchairs for movement on hard surfaces with obstacles.
