The LV-T30 Liquid Fuel Engine is the first liquid-fuel engine available in career mode. It 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-T30 is the first liquid fuel engine with throttle control, shutdown and restart capabilities, making it easier to control vehicles safely and accurately. It also has nearly twice the specific impulse of the solid motors that went before it. This and other axially mounted engines cannot be placed radially and must be directly below a non-empty liquid fuel tank to produce any thrust. Since the tanks can be placed radially, the LV-T30 can be the basis of liquid-fueled strap-on boosters in parallel configurations. Since the engine lacks thrust vector control, other means must be incorporated to make sure the vehicle remains pointed in the right direction, such as parts with reaction wheels, aerodynamic fins and control surfaces, and parallel operating gimbaled engines such as the LV-T45.

Product description

Although criticized by some due to their not insignificant use of so-called "pieces found lying about", the LV-T series engines have proven themselves as comparatively reliable. The T30 model boasts a failure and rattly bits ratio below the 50% mark, this has been considered a major improvement over previous models by engineers and LV-T enthusiasts.
