Двигательная установка. RS-68. [Редактировать]

Жидкостный ракетный двигатель. Развитие двигателя было начато в 1990-х с целью получения более дешевого и простого в производстве двигателя для первой ступени ракеты-носителя Дельта-4, обладающего большой тягой. Двигатель РС-68 был разработан в лаборатории Propulsion and Power компании Рокетдайн. Управление вектором тяги осуществляется гидравлической системой, диапазон дросселирования от 57 до 102 %.

Основной целью программы разработки RS-68 было создание простого двигателя, который был бы экономически выгоден при одноразовом использовании на ракете-носителе. Для того, чтобы достичь этой цели, двигатель имеет на 80 % меньше деталей по сравнению с двигателем многократного использования SSME (RS-24). Простота и дешевизна двигателя отразилась в худших показателях эффективности по сравнению с RS-24: соотношение тяги к массе RS-68 значительно ниже, удельный импульс меньше на 10 %. Преимуществом является меньшая стоимость постройки нового двигателя: для того, чтобы сделать новый RS-68 для программы Боинга ракеты-носителя Дельта-4, требуется 14 млн американских долларов.

Эта конструкция, использованная впервые в СССР, включает в себя внутреннюю и внешнюю оболочку топливопроводов, сваренных через разделители, которые формируют охлаждающие каналы. Этот метод приводит к более тяжёлой конструкции, но гораздо дешевле по сравнению с трубочно-стенным дизайном (конструкции данного типа используют сотни трубок, согнутых по форме камеры сгорания и сваренных вместе), который используется в других американских двигателях. Нижняя часть сопла имеет коэффициент расширения 21,5 и выполнена из абляционного материала. Облицовка внутренней части сопла предназначена для выгорания в ходе работы двигателя, что имеет своей целью отвод тепла и объясняет необычно яркий цвет газовой струи на выходе из сопла, полученной в результате горения водорода и кислорода. Такая конструкция также имеет большую массу по сравнению с трубочно-стенным дизайном сопел, используемым другими двигателями, но также проще и дешевле в производстве. В то время как первоначальный дизайн был разработан в лаборатории Рокетдайн в Парке Канога (Canoga Park), Калифорния, там же где был разработан SSME, первые пробные образцы двигателей были собраны в полевой лаборатории Санта Сузана, где разрабатывались и испытывались двигатели ракеты-носителя Сатурн-5 для программы Аполлон полетов на Луну. Первые стендовые испытания RS-68 производились на базе лаборатории ВВС США Эдвардс, позднее в космическом центре НАСА имени Стенниса. Первое успешное стендовое испытание на базе Эдвардс было завершено 11 сентября 1998 года, первое успешное использование двигателя и успешный запуск ракеты-носителя выполнены 20 ноября 2002 года. Двигатель RS-68 является частью унифицированного разгонного блока, используемого для создания пяти вариантов ракеты-носителя семейства Дельта-4. Самый тяжёлый вариант, использованный на 2009 год, включает в себя три блока CBC, соединённых вместе. Потенциально возможно использование семи таких блоков в одной ракете-носителе.
