Game On! Musk announces test fire of the engine for the Mars Colony Transport
2016-09-26


The MCT will have a huge cluster of these engines.

Production Raptor goal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar.

Chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio.

It is pumping to 45-50 MPa with multi-stage pumps.

Pretty close to a ~14 foot diameter nozzle for the vacuum form of the engine and 5 foot for the booster form.

Next to the Saturn V's 1st stage F-1, this will be the most powerful single nozzle rocket engine ever produced!
