Description:
The SABRE Engine type is to be developed by Singan and Kazemura to develop a new form of efficient propulsion for a planned SSTO and new commercial hyper-sonic aircraft that is cost effective, and relatively cheap compared to other forms of propulsion. The engine will operate as a hybrid hypersonic precooled air-breathing engine; functioning as a single internal cycle, it does feature however two modes of operation. So after take-off as more air is compressed by this turbo-compressor after intake, it is then cooled resulting in this high pressure ratio in the combustion chamber to allow for higher thrust and speeds at high altitudes.

Since the air temp is made cool, it allows for lightweight alloys for the engine to be utilized; allowing for a more effective thrust to weight ratio both needed and useful in achieving orbit and making orbital maneuvers. After it reaches about Mach 5, it shuts off the inlet cone, and becomes a closed-cycle using on board stores of oxygen instead. It should be noted the ascent profile is fairly steep for best results.

The commercial variant removes the rocket oriented features, and increases bypass features to allow for even greater efficiency.

You can find a more extensive list of stuff that's happened in role play here...if people bothered to add it.
