FIELD: transportation.
SUBSTANCE: invention relates to water transport and can be used for high-speed vessels year-round operation. Amphibious wheel propulsor (AKD), which is a body of revolution, comprising recesses and ribs along periphery. Recesses made on periphery in 20–40 equal angular sectors of full circle, have bucket-like shape, and separating them and limiting on sides ribs form rolling surface.
EFFECT: increased efficiency and reliability of amphibious propulsor during operation.
