FIELD: engines.
SUBSTANCE: invention relates to underwater transport propulsors, namely, to underwater robots propellers. Propulsor with movable spokes has cylindrical rim, rim drive shaft and radial spokes and equipped with cam and cam drive shaft. Rim rotational axis coincides with axis of shaft rotation. Cam has possibility to rotate around its drive shaft axis and be fixed at any angle. Radial spokes have flat part, which plane is parallel to axis of rotation, and cylindrical part, which protrudes beyond rim. Spoke flat part by one end passes through hole in rim cylindrical surface, and at opposite end has slot for hook-type sliding engagement with cam flat part. During cylindrical rim rotation radial spokes have possibility to perform reciprocal motions.
EFFECT: enabling efficient underwater transport motion both in water and on underwater soil or ooze.
