FIELD: engine building.
SUBSTANCE: invention relates to screw propulsion units. Screw propulsor comprises two cylindrical rotors with screw flanges on each, equipped with rotation mechanism, and rotary head. Arched-type bracket is mounted on cantilever extension of shafts of cylindrical rotors and supports a rotary head support in lengthwise plane of propulsor – self-orienting spherical elastic wheel with its diameter exceeding that of cylindrical rotors. At that, self-oriented spherical elastic wheel on cantilever arm bracket can be on two ends of cylindrical rotors.
EFFECT: broader functional capabilities of the screw propulsor on solid surfaces.
