FIELD: engines and pumps.
SUBSTANCE: invention relates to the screw propulsion unit. Screw propulsion unit comprises rotary heads mounted on the hollow rotor with the multiple spiral screw. Rotary heads of the spherical design are equipped with individual rotational drives and mounted at the ends of the screw rotor on forks with semi-axes serving as semi-axes for the screw rotor. In this case, one of the two or both spherical heads can be freely rotating.
EFFECT: extension of the screw propulsion unit functionality is achieved.
