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).

The manufacturer's name seems to be misspelled. Usually it is but this part is, according to the configuration, manufactured also by the Rockmax Conglomerate. In the description text however uses the common spelling.

Usage

This is the only hybrid engine ingame, it is 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.

Manufacturer's description

The R.A.P.I.E.R (Reactive Alternate-Propellent Intelligent Engine for Rockets) is a joint venture between C7 Aerospace and the Rockomax Conglomerate. Designed to fill a gap in the design requirements for sustainable single stage to orbit aircraft, this engine combines the best of rocket and air-breathing thrust technology
