Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… … Wikipedia
Supercavitation propeller — The supercavitation propeller is a variant of a propeller for propulsion in water, where cavitation (formation of water vapour) is actively employed to gain increased speed by reduced friction. This article distinguishes a supercavitation… … Wikipedia
Supercavitation — is the use of cavitation effects to create a large bubble of gas inside a liquid, allowing an object to travel at great speed through the liquid by being wholly enveloped by the bubble. The cavity (the bubble) reduces the drag on the object and… … Wikipedia
