As a pure rocket, its thrust-to-weight ratio is worse than any conventional rocket. Its specific impulse is in the middle of the pack compared to other rocket engines. The closed-cycle performance is merely mediocre. Top speed is ~2,100 m/s in kerbins atmosphere (mach 6.2) On the other hand, it delivers better performance than the J-X4 "Whiplash" Turbo Ramjet Engine at high speeds (~1000 m/s and higher) and altitudes (~17,000 m and higher), making it a good choice for high-speed atmospheric flight. The air-breathing mode has lower specific impulse than the other jets, though still a order of magnitude higher than most rocket engines. Like other jet engines, the air-breathing mode only works in the atmospheres of Kerbin or Laythe. Unlike the other jet engines, the R.A.P.I.E.R. This engine is one of the few engines that do not provide electric charge when active, another example being the LV-909 engine. The hybrid feature makes this engine especially useful for single-stage-to-orbit designs as it saves the weight of a separate engine. 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. 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. However, the description text used the common spelling and the manufacturer entry was fixed in 0.24. Instead of Rockomax Conglomerate an o was missing attributing it to the Rockmax Conglomerate. Prior to 0.24 one of the manufacturers seems to be misspelled. This is the first engine which has two different manufacturers. This is one of the first stock engine which has multiple nozzles incorporated into one part (four in this case). 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. It has the feature to auto adjust, changing between jet and rocket mode automatically when it runs out of intake air. ![]() It can change between an airbreathing jet and a liquid fuel engine. ![]() Engine (Reactive Alternate-Propellent Intelligent Engine for Rockets) is a hybrid engine.
