Game On! Musk announces test fire of the engine for the Mars Colony Transport
 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! Posted by: 3dc 2016-09-26 |
