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 was the first 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 specific impulse as the LV-T30 Liquid Fuel Engine, the more complex LV-T45 has slightly less thrust resulting in a longer burn time at the same fuel amount. Parallel ignition of several LV-T30 and LV-T45 engines at lift-off can lead to maximized thrust without losing control.

However, the LV-T45 has a mass of 1.5 tons and as said before, less thrust compared to the LV-T30, which masses 1.25 tons. This means a worse TWR.

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.

Description

The LV-T45 engine was considered another 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 less powerful engine in comparison with earlier LV-T models.
