Пока интересны только новые планы. Вот планы почему-то изменились...
Если часть двигателей выключить - не вполне очевидно что их удастся потом снова включить.
Ну им вообще-то пока что платили только по результатам. Едва ли их допускают к распилу.
Идея отделять боковые блоки и дросселировать центральный совершенно логична, но Merlin 1C не дросселируемый. Если часть двигателей выключить - не вполне очевидно что их удастся потом снова включить.
Falcon 9 Heavy OverviewThe Falcon 9 Heavy will be SpaceX’s entry into the heavy lift launch vehicle category. Capable of lifting over 28,000 kg to LEO, and over 12,000 kg to GTO, the Falcon 9 Heavy will compete with the largest commercial launchers now available. It consists of a standard Falcon 9 with two additional Falcon 9 first stages acting as liquid strap-on boosters. With the Falcon 9 first stage already designed to support the additional loads of this configuration and with common tanking and engines across both vehicles, development and operation of the Falcon 9 Heavy will be highly cost-effective. Initial architectural work has already begun, and we currently anticipate first availability of the Falcon 9 Heavy in 2010.Length: 54 m (178 ft)Width: 3.6 m (12 ft)Mass: 885 t (1,950 kbl)Thrust on liftoff: 12.2 MN (2,750 klbf)Mass to LEO: 28,000 kgMass to GTO: 12,000 kg

И уж совсем теряюсь в догадках - что в размере 19,5 т Маск собирается выводить на ГПО? Даже даблшотов таких в природе не существует и не планируется.
Будут трипл-шоты. Как раз в 19 тонн влезут.
Дык зачем там еще РБ, если двигатель верхней ступени специально сделан с повторным включением?
и в конце концов получилось, что трехблочный вариант получается вот такой афигенно мощный, ни туда, ни сюда.
Цитата: Belll от 14 Фев 2010 [17:33:01]Дык зачем там еще РБ, если двигатель верхней ступени специально сделан с повторным включением?Для выведения не на ГПО, а непосредственно на ГСО. У военных иногда возникает такая потребность.
Может они собираются сделать свое предложение по пилотируемой лунной программе?
Ну, будут 6 миллиардов на коммерческий космос. Это никак не низкая орбита, с такими деньгами.
