ЦитатаИзвиняюсь, а поменять местами горючее и окислитель на 1-й ступени там не предлагалось? :roll:
ЦитатаЕще есть такой вариант:- первая ступень обычная, поскольку жестко завязана на габаритах,- третья водородная порядка 45-50 т (максимум по длине) на базе того же Шторма, с 4-мя двигателями,- а вторая - увеличенная старая, догоняется до максимальной массы, которую позволяют форсированные двигатели первой ступени при сохранении прежней тяговооруженности.По распределению ХС конечно неоптимально, но ПН все равно получается до 30 т на ЛЕО и порядка 9-10 т на ГПО.
Цитата:wink: Это как посмотреть! Прикинь сам, сколько выводил бы такой Протон на ГСО, если водородная ступень работала как Центавр на Атласе (на половине двигателей)
ЦитатаНеизвестно потому что до серьёзных работ дело так и не дошло.
ЦитатаNew Proton variantThe Salyut Design Bureau has announced that, beginning in 1994, it intends launching a new variant of the Proton carrier rocket which will be able to place larger payloads into space. The modernised version will be able to place 23.7 tonnes into a low Earth orbit (the current version can loft 21.1 tonnes into the same orbit), 4.5 tonnes into geostationary orbit (2.3 tonnes currently) and 8 tonnes into an interplanetary trajectory (5.7 tonnes currently).

ЦитатаThe Soviet Union is planning to introduce uprated versions of its Proton SL-12 and SL-13 expendable launch vehicles, with a possible first flight as early as 1994. Both versions of the booster...will have uprated second and third stages fuelled by nitrogen tetroxide and UDMH. The SL-12's D1e liquid oxygen/kerosene fourth stage will be replaced by a cryogenic liquid-oxygen/liquid-hydrogen upper stage. The new model will fly from the upgraded Proton launch pads at Baikonur, shut down in the 1970s.The uprated version of the three-stage SL-13 booster will be able to place 23.7t into low-Earth orbit. The existing vehicle can launch 21t...The new version of the four-stage SL-12 will increase its capability to place satellites directly into geostationary orbit from 2.2t to 4.5t. Interplanetary flights with payloads weighing up to 8t will be possible, an increase of 2.3t on current Proton performance.The first missions of the upgraded SL-12 are expected shortly to place the next-generation Soviet communications satellites, designated Gelikon and Granat, into geostationary orbit. These satellites, weighing about 3.7t, are likely to replace the Soviet Union's existing Gorizont and Ekran fleet.
