Cavitation, английский
- Кавитация - явление, возникающее на плавнике на очень большой скорости (срыв потока), за чем неизбежен спин-аут (spin out)
- Formation of an air or vapor pocket (or bubble) due to lowering of pressure in a liquid, often as a result of a solid body, such as a propeller or piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the violent collapse of a vapor bubble. cavitation can occur in a hydraulic system as a result of low fluid levels that draw air into the fluid, producing tiny bubbles that expand followed by rapid implosion, causing metal erosion and eventual pump destruction.
- Кавитация
- Кавитация, образование пустот
- A phenomenon in the flow of water consisting in the formation and the collapse of cavities in water.
- The forming of a cavity
- The formation and collapse of air bubbles created by a ship’s propeller. this reduces effective thrust, creates noise detectible by an enemy, and may cause structural damage.
- The formation of a pocket (bubble) of air or vapor in a liquid, typically resulting from the swift movement of a solid object (such as a propeller or piston) through the liquid. also, the pitting and wearing away of metal or other solid surfaces caused by the collapse of air/vapor pockets in surrounding liquid.
- Describes the continous pumping of mud from surface-level mud tanks, down the drill pipe, out the drill bit nozzles, and through the gap between the drill pipe and the borehole to the surface. this movement carries rock cuttings via the shale shaker to the mud system.
Propulsion, английский
- (реактивное) движение; силовая [двигательная] установка; двигатель
- Cредства движения; движение
- Marine propulsion is the act of moving an object through the water or across its surface. poles, paddles, and oars were the earliest forms, while sails represented the most significant historical method. today, common types are underwater propeller, water-jet, paddle wheel and, experimentally, magnetohydrodynamic drive.

Song of the seabees, английский
Usn construction battalions have their own song, written in 1943 with words by sam m. lewis to music by peter de rose. the original wartime text made specific reference to pearl harbor; two verses of an updated and less specific version are: we’re seabees of the navy we can build and we can fight we’ll pave the way to victory and guard it day and night no matter what our mission we’ll uphold our proud tradition we’re seabees of the navy bees of the seven seas.
Sonar dome, английский
A streamlined, watertight enclosure that provides protection for a sonar transducer, sonar projector, or hydrophone and associated equipment, while offering minimum interference to sound transmission and reception by reducing the effects of turbulence, wave slam, and minor collision. early versions were keel-mounted, made of steel-reinforced “egg box” construction, but they have now evolved into high performance lightweight shells, bow-mounted, relying on the structural and acoustic properties of advanced fiber composites.
