FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely to waterway propulsion, and can be used as a propulsion vessel. The propeller contains a hub with loop-shaped blades. The profile of the blades is made of double-sided segment design, and the relative width of the blade and the relative spacing of the front and rear parts of the loop-shaped blade are variable.
