The LV-N Atomic Rocket Motor is a low-thrust, high-efficiency rocket engine. It is modeled after the real-world nuclear thermal rocket, which uses a fission reactor to heat its propellant and force it out of the rocket nozzle to generate thrust (as opposed to a normal rocket, which ignites the propellant and uses the energy released by the resulting chemical reaction for that purpose).

Usage

The LV-N has low thrust and a very high mass, giving it the worst thrust-to-weight ratio of all liquid engines. Its Isp while in atmosphere is also quite poor, making it not recommended for operation within atmospheres or for landings on larger bodies.

However, when outside the atmosphere, its efficiency becomes superb with a vacuum Isp of 800 s, by far the highest of any liquid fuel engine. This remarkable efficiency makes it quite popular for upper stages as it is ideal for interplanetary travel.

It will overheat when run at full throttle, but it will usually stabilize before completely filling the overheat bar. As of version 0.23, it will quickly overheat and explode when placed directly under a Rockomax Jumbo-64 Fuel Tank.

It is also quite long, being almost exactly the same length as a Mainsail engine. LV-N engines on a landing stage require some interesting structure designs to get the landing gear low enough to clear the bottom of the engine.

Yes, I know this is wrong. NTRs don't actually burn fuel and oxidizer, but we don't want to jump into making separate tanks for the two yet.

Excerpt from the part.cfg

Trivia

  • The description of this part is a reference to the Douglas Adams humorous sci-fi novel "Mostly Harmless"
  • Unlike real-world nuclear thermal rockets, the LV-N consumes both liquid fuel and oxidizer. This due to programming constraints, as stated in its parts.cfg file, and Squad's unwillingness to add another propellant type. Real NTRs run on liquid hydrogen, but are capable of using other propellants at lower efficiencies.
