The R.A.P.I.E.R. Engine (Reactive Alternate-Propellent Intelligent Engine for Rockets) is a hybrid engine. It can change between an airbreathing jet and a liquid fuel engine. It has the feature to auto adjust, changing between jet and rocket mode automatically when it runs out of intake air. This engine is an in-game counterpart of the real life SABRE engine, which is also visible in the naming as both are named after swords.
This is the first stock engine which has multiple engines incorporated into one part (four in this case).
This is the first engine which has two different manufacturers. Prior to 0.24 one of the manufacturers seems to be misspelled. Instead of Rockomax Conglomerate an o was missing attributing it to the Rockmax Conglomerate. However, the description text used the common spelling and the manufacturer entry was fixed in 0.24.
Usage
This engine has two modes of operation. An AirBreathing mode in which it runs on liquid fuel and intake air like a jet engine and a ClosedCycle mode in which it runs on liquid fuel and oxidizer like a rocket engine. The air-breathing mode is far more fuel-efficient and delivers slightly more thrust, but just like normal jet engines it only works in the atmospheres of Kerbin or Laythe.
The engine can either be set to switch automatically to closed-cycle when the intake air runs out or it can be switched manually between the two modes.
The hybrid feature makes this engine especially useful for single-stage-to-orbit designs. The engine has less efficiency than comparable jet or rocket engines, but because it can switch between modes, it may be a better choice than a Toroidal Aerospike Rocket for orbital insertion. This engine is one of the few engines that do not provide electric charge when active, another example being the LV-909 engine.
