screw propeller

n
(Mechanical Engineering) an early form of ship's propeller in which an Archimedes' screw is used to produce thrust by accelerating a flow of water

She was a screw propeller of eight hundred tons, a fast sailer, and the very vessel that had been sent out to the polar regions, to revictual the last expedition of Sir James Ross.
Specifically, the vessel utilizes the hull form (optimized with the latest development technologies) and a screw propeller, (combined with the Mitsubishi Reaction Fin) to improve overall propulsion efficiency.
Brunel had decided to give it an iron hull, which allowed the vessel to be much larger than if it had been made of wood, and to fit a screw propeller, then an experimental technology.
Brunel built her from iron and the previously unheard of 1000 hp steam engine and screw propeller ensured Great Britain really did rule the waves.
Among the existing fish robots, several robots like RoboTuna and VCUUV are inspired by tuna which is a pelagic fish whose locomotion is highly efficient [10] (bear in mind that Bandyopadhyay [11] believes that the efficiency of biomimetic swimming robot is not higher than screw propeller robots but animals do show superior manoeuvrability in swimming).
* the effect of the water flow produced by the screw propeller on the ship board.
Therefore the outboard water around a screw propeller, where the cavitation reaches the highest level, is mostly suitable for cooling the surface of marine motors and using in sea water distillation equipment.
They not only gave us the first golden lager in 1842, but introduced the world to the screw propeller (Josef Ressell in 1826), the gel contact lens (Otto Wichterle) and the arc lamp (Frantisek Krisik).
