Двигательная установка. LE-7A. [Редактировать]

LE-7A это обновленная версия двигателя LE-7. Основной дизайн остался неизменным. Модификация 7A была произведена с целью упрощения процесса производства и сборки. Кроме этого, реконструкция двигателя была произведена с целью его адаптации к использованию на ракетах серии H2A.

Изменения по сравнению с базовой версией:

  • снижение объемов сварочных работ за счет изменения конструкции магистралей (снижение свариваемых элементов с 935 до 458, а частей со 166 до 99);
  • изменение топливного и окислительного индукторов;
  • сокращение числа деталей в инжекторе;
  • уменьшение размера камеры сгорания (снижение числа элементов с 452 до 295, а числа сварных деталей с 209 до 24);
  • понижение импульса, по сравнению с базовой версией.
