The LV-T45 Liquid Fuel Engine is an engine which requires fuel from external liquid fuel tanks, and must be either connected beneath them or be on the receiving end of a fuel line.
Usage
The LV-T45 is very similar to the LV-T30 Liquid Fuel Engine. It is slightly less powerful and slightly heavier, but it has thrust vectoring and higher specific impulse in vacuum conditions. Thrust vectoring means that the engine is able to slightly change the angle it is pointing to, which gives the player the ability to steer the rocket while the engine is burning. This allows efficient control of the rocket when it is most needed - during ascent and orbit correction burns.
Parallel ignition of several LV-T30 and LV-T45 engines at lift-off can lead to maximized thrust without losing control. But keep in mind that having the same specific impulse with less thrust means that it burns slightly longer than the LV-T30 with the same amount of fuel.
Like LV-T30, the LV-T45 cannot be placed on radial decouplers and are typically reserved as a main engine after lift-off. The LV-T45 must be directly below a non-empty fuel tank to produce any thrust.
Product description
| “ | The LV-T45 engine was considered a breakthrough in the LV-T series due to its Thrust Vectoring feature. The LV-T45 can deflect its thrust to aid in craft control. All these added mechanics however, make for a slightly smaller and heavier engine in comparison with other LV-T models. | ” |
