One of the most commonly used Jet engines in KSP. 0.16

A jet engine is an air-breathing engine which uses onboard fuel and combusts it with the oxygen drawn from the atmosphere. Due to the lower air pressure at higher altitudes its thrust output varies accordingly.

  1. The R.A.P.I.E.R. Engine is a combination of liquid fuel and jet engine. Only the jet engine properties are shown.


Usage

Unlike rocket engines, a jet draws oxygen from the atmosphere rather than taking it from an on-board tank. This is represented in-game by a much lower rate of fuel consumption. This engine cannot function effectively at a height of much more than 5km, but it is much more efficient to use jet engines in the lower atmosphere. Jet engines do not perform in the same manner as rocket engines. Since Jet engines rely on a turbine to compress fuel and atmosphere together in order to produce thrust, it takes time to change speed. Also if the throttle is too low the engine will stall. By contrast, rocket engines give instant response to control input.

Currently, jets do not require you to fit air intakes to your spacecraft and function independently of whether you use a fan intake or not.

Advantages of Jet Engines

  • Provides excellent fuel efficiency within an atmosphere
  • All current jet engines provide thrust vectoring for greater maneuverability
  • Excellent power to weight ratio

Disadvantages of Jet Engines

  • Cannot be used outside of an atmosphere
  • Thrust output changes depending on altitude
  • Engine requires time to spool up to maximum thrust potential
