Waterfront
| Морской словарь |
- [1] the wharf or dock area of a city. [2] land at the edge of a stream, harbor, or other body of water. waterjet:marine propulsion technology is moving quickly to offer alternatives to the venerable propeller, one of these being jet propulsion. basically, this depends on differences in the mass-flow of water, which enters and exits a jet drive at differing velocities. a pump draws in water through a mesh that stops foreign objects from entering. an impeller then forces the water out of one or more nozzles at high pressure, accelerating the craft in the opposite direction. in some systems, forward and reverse motion is infinitely controllable through a deflector that diverts thrust forward or aft; in others, the nozzle(s) can turn a full 360 degrees to achieve maximum thrust in either direction. steering is accomplished by directing exit flow, much like directing the thrust of a submerged propeller system. the exit jet does not have to be underwater, since propulsion will be equally good if it thrusts against the air. provided engine and jet drive are well matched, water jet propulsion can be more efficient than conventional propellers. for vessels designed to go faster than 30 knots, especially those that can be called upon to operate in shallow waters, waterjets turned by diesels or gas turbines are often the preferred propulsion option. also called hydrojet propulsion, and see cycloidal drive.

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.
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).
Differences, английский
Цифровой избирательный вызов, цив - технология радиосвязи, при которой предварительное согласование канала вызова другого судна осуществляется не широковещательно на голосовом канале, а на отдельном цифровом канале. после согласования рабочего канал
Controllable, английский

Waterspace management, английский
The allocation of surface and underwater spaces as areas for antisubmarine warfare, together with the implementation of procedures to permit the rapid and effective engagement of hostile submarines, while preventing inadvertent attacks on friendly submarines.
Waterborne, английский
Afloat.
