Editing Merlin

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==

The nozzle is an inexpensive, expendable [[Ablative cooling|ablatively cooled]] carbon fiber composite.
