The Merlin engine is a RP-1/liquid oxygen gas-generator cycle rocket engine. The Merlin engine was developed for use on the Falcon 1, Falcon 5 and Falcon 9 rockets by SpaceX and is designed for sea recovery and reuse.
Engine details[edit]
The nozzle is an inexpensive, expendable ablatively cooled carbon fiber composite.
Engine revision 1B has been enhanced over the 1A with a turbine upgrade (from 1490 kW to 1860 kW)
