The 48-7S "Spark" Liquid Fuel Engine is a liquid fuel engine for small craft.
Product description
| “ | The 48-7S may be small, but it packs quite a punch for its size. This little engine is a testament to how larger does not always means more advanced, at least according to Rockomax's marketing department. The box it comes in is pretty cool, in any case. — Rockomax Conglomerate |

Usage
The Spark is a size 0 engine, typically placed on the bottom of a stage. Its specific impulse and thrust-to-weight ratio are similar to the LV-T45 "Swivel" Liquid Fuel Engine, and it can be used to serve a similar function. However, its unique size and mass make it a good upper stage engine; it has a reasonable specific impulse, and a low mass. By using a Spark instead of a heavier LV-909 "Terrier" Liquid Fuel Engine, a vessel's reduced dry mass may allow for greater delta-V.
The 24-77 "Twitch" Liquid Fuel Engine is the radial variant of the Spark. It has equal thrust, but has a lower specific impulse.
Variants
As of version 1.6 this engine has three models that can be switched in the editor.
The different variants of the engine
Trivia
- The 48-7S "Spark" Liquid Fuel Engine was originally from the KSPX parts mod.
- Prior to version 1.7, due to its relatively high Isp and thrust to weight ratio, the 48-7S was remarkably capable in ascent, transfer, and lander roles and had a thrust to weight ratio second only to the Kerbodyne KR-2L Advanced Engine and the S3 KS-25x4 Engine Cluster.
Changes
- Atmospheric Isp increased from 260 to 265
- Mass increased from 0.1 to 0.13
- Atmospheric Isp decreased from 270 to 260
- New model and texture
- Added 3 variants
- Thrust increased to 20 kN and 320 specific impulse in vacuum.
- Cost increased from 200 to 240.
- Thrust decreased to 18kN.
- Thrust increased from 20 to 30 kN, description changed.
- Initial release
