The LV-909 Liquid Fuel Engine is a liquid fuelled rocket engine.
Usage
The LV-909 is the second Liquid Fuel engine with thrust vector control, that allows efficient control of the rocket when it is most needed - during ascent and orbit correction burns. Despite having the same fuel specific impulse as LV-T30 and LV T-45 Liquid Fuel Engines, the much smaller and lighter LV-909 has dramatically less thrust (and longer burn time at the same fuel amount). The low thrust makes the LV-909 unsuitable as a main engine on most lower stages, but the low mass allows for more efficient upper stages. More importantly, the LV-909 is short enough that LT-2 Landing Struts can extend past it. Because of this, the LV-909 is the primary choice for lander engines in 0.14.x.
Like LV-T30 and -45, the LV-909 are not placeable on Radial Decouplers. The LV-909 must be directly below a non-empty liquid fuel tank, or fed by an fuel line to produce any thrust.
The thrust vectoring on this engine tends to be less useful than on the LV-T45, due to both the reduced gimbal range, and use on lighter rockets.
Description
| “ | The 909 model was initially received with some skepticism by spacecraft engineers, as it defied the long-standing convention that "More Power!" is always better. Despite this, the 909 series has found its place in the spacecraft construction world, being particularly useful as a final stage and landing engine. — Jebediah Kerman's Junkyard and Spaceship Parts Co. |
