Merlin 1г—1 [ Linux SIMPLE ]

The consists of high-performance liquid rocket engines developed by SpaceX to power their Falcon 1 , Falcon 9, and Falcon Heavy rockets. Operating on a gas-generator open-cycle using RP-1 (rocket-grade kerosene) and liquid oxygen (LOX), they are renowned for their world-leading thrust-to-weight ratio and design for reusability. Key Variants and History

: An upgraded variant of the 1A with a more powerful turbine; it was never used on a flight vehicle before SpaceX shifted to regenerative cooling. Merlin 1Г—1

: Uses a triple-redundant flight computer system on each engine to ensure high reliability during launch. : Uses a triple-redundant flight computer system on

: The initial version used an expendable ablatively cooled carbon-fiber nozzle. It flew only twice on the Falcon 1 (2006–2007). : One center Merlin engine is fired during

: One center Merlin engine is fired during the final landing burn to enable first-stage vertical landings.

: Drives both the LOX and RP-1 impellers. It also provides high-pressure fuel for hydraulic actuators , eliminating separate hydraulic systems.
