The LFB KR-1x2 will be first part which contains both a liquid fuel tank and a liquid fuel engine. Usually only solid rocket boosters using solid fuel contain both, because solid fuel can't be transferred. Unlike solid rocket boosters this liquid fuel booster can run longer by pumping additional liquid fuel and oxidizer to the part. It can also be throttled.
This booster contains two engines at the bottom which are added radially so the base of the booster is wider than a usual large tank. It also doesn't allow any parts below it. It contains the same amount of fuel like the Rockomax Jumbo-64 Fuel Tank. The thrust is higher an than the Rockomax "Mainsail" Liquid Engine, and is thus the most powerful large sized engine. Its specific impulse is also higher than the Mainsail's one. Even in the atmosphere the booster's engines have only a specific impulse which is 10 seconds below that of the vacuum specific impluse of the Mainsail. But it is quite possible that those values will be tweaked to maintained a balanced setting.
Manufacturer's description
“ | This liquid fuel booster system was designed to allow for finer control of launches instead of relying solely on single engine solid rocket boosters it employs two modified KR-1 engines as the source of its immense lifting power. — Kerbodyne |
