Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller , or less frequently, in pump-jets , an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.

Understanding Different Operational Modes Of Shaft Generator On Ships

Without a source of power, these mammoth cruise ships would be nothing more than hotels drifting aimlessly. So what are the options? Many older cruise ships use reciprocating diesel engines to generate power for propulsion. The power of the engine is fed through a transmission to propeller shafts. Transmissions determine the revolutions of the propellers, much like the transmission transfers the engine RPM into manageable speeds to power the rear wheels in our cars. Modern cruise ships use either gas turbine or diesel electric engines as their power source for propulsion, as well as for the ship's systems. The larger the cruise ship, the greater the demand for electrical power.

How Cruise Ships Work

The shaft generator on a ship is an excellent example of a waste heat recovery system , which not only utilizes the waste energy from the engine but also supplies the additional work to the propeller shaft when the main engine is underperforming. The Shaft Generator — Motor circuit breaker is usually closed, if not, an operator can close the circuit breaker via the PMS panel.

Но только путем сброса информации, хранящейся в Банках Памяти, и установки затем новых образов. В общем, я упомянул обо всем этом только для того, чтобы продемонстрировать, как город сохраняет себя физически. Вся суть в том, что в Диаспаре есть аналогичные машины, сохраняющие нашу социальную структуру.

Они следят за всеми изменениями и корректируют их прежде, чем те станут слишком заметными. Как они это делают. Я не знаю. Может быть, они отбирают тех, кто появляется из Зала Творения. Может быть, они подправляют образы наших личностей: мы-то думаем, что обладаем свободой воли, но как можно быть в этом уверенным.

Так или иначе, проблема была решена.

Они были в космосе одни, наедине со звездами и странно съежившимся Солнцем. Да, Земля пропала, словно ее никогда и не существовало во Вселенной. Снова последовал рывок - и возник едва слышный шелест, точно генераторы впервые выбросили ощутимую долю своей мощи.

На миг показалось, что ничего особенного не произошло; но затем Элвин сообразил, что Солнце также исчезло, а звезды медленно ползут мимо корабля. Элвин на секунду обернулся - и увидел абсолютную пустоту. Небо позади было полностью поглощено полусферой тьмы.

Прямо на глазах звезды уходили в нее и пропадали, точно падающие в воду искры.

Олвин не тратил времени зря и немедленно принялся узнавать все что можно о Хедроне. Как всегда, основным его источником информации был Джизирак. Старый наставник дал ему строго фактический отчет о своей встрече с Хедроном и добавил к нему то немногое, что ему было известно об образе жизни Шута. В той мере, в какой это вообще было возможно в Диаспаре, Хедрон вел уединенную жизнь: никто не знал ни где он обитает, ни каковы его привычки.

Последняя по времени шутка, которую он отмочил, была, в сущности, совсем детской проказой, повлекшей за собой полный паралич всего городского транспорта.

Ничего иного он и помыслить себе не. -- Проблема, волнующая тебя, очень стара,-- говаривал Джизирак Олвину.

Ведь любой мог обнаружить путь, по которому он уже прошел, и бессчетное количество раз за минувшие тысячелетия другие, должно быть, заходили почти так же. Те, ранние Неповторимые, к примеру, -- что сталось с. Очень -- может быть, что он просто оказался первым, кому повезло.

Когда Черное солнце умрет, он снова станет свободен. Сказать, насколько далеко в будущем лежит этот день, не представляется возможным. Коллитрэкс умолк, словно бы забывшись в собственных размышлениях, совершенно безразличный к тому, что на него глядели глаза всего мира.

Воспользовавшись этим долгим молчанием, Олвин стал оглядывать тесно сидящих вокруг него людей, стремясь прочесть, угадать, что у них на уме теперь, когда они познали откровение и ту таинственную угрозу, которая отныне призвана заменить миф о Пришельцах.

Загадки всегда завораживали меня, а в Диаспаре их так мало. Кроме того, мне кажется, что судьба, возможно, готовит нам такую шутку, по сравнению с которой все мои шутовские проделки будут выглядеть куда как скромно.
