Событие | Да |
The LFB KR-1x2 is the first part that 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, both: using main throttle and thrust limiter tweakable. Minimum thrust required for booster to lift its own weight is 17.5%.
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 does not allow any parts to be attached below it. It contains the same amount of fuel as the Rockomax Jumbo-64 Fuel Tank. The thrust is higher than the Rockomax "Mainsail" Liquid Engine and is thus the most powerful large-sized engine. However, its Isp is significantly (30 s) lower than that of the Mainsail at all altitudes.
Описание изделия
« | 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. | » |
« | This liquid fuel booster system is a very purposeful piece of engineering. Instead of relying on single engines or solid rocket boosters, the KR-1x2 employs two modified KR-1 engine, fed by a built-in fuel system, as the source of its immense lifting power. All that self-contained goodness comes at the cost of not having a mounting point for its underside, and not being quite as efficient as dedicated engines. It also comes at quite a literal cost as well. — Kerbodyne 0.24 |
