SpaceX’s Merlin 2 LOX/RP-1-fueled engine on a gas-generator cycle, capable of a projected 7,600 kN (1,700,000 lbf) of thrust at sea level and 8,500 kN (1,920,000 lbf) in a vacuum and would provide the power for conceptual super-heavy-lift launch vehicles from SpaceX, which Markusic dubbed Falcon X and Falcon XX.
SpaceX has developed two kerosene-based engines through 2013, the Merlin 1 and Kestrel, and has publicly discussed a much larger concept engine high-level design named Merlin 2. Merlin 1 powered the first stage of the Falcon 1 launch vehicle and is used both on the first and second stages of the Falcon 9 and Falcon Heavy launch vehicles. The ...

SpaceX's Merlin and Kestrel rocket engines use a RP-1 and liquid oxygen ("kerolox") combination. Raptor has about triple the thrust of SpaceX's Merlin 1D engine, which powers the Falcon 9 and Falcon Heavy launch vehicles. Raptor was conceived to burn hydrogen and oxygen propellants as of 2009. [36]
Both stages are equipped with Merlin 1D rocket engines. Every Merlin engine produces 854 kN (192,000 lb f) of thrust. [70] They use a pyrophoric mixture of triethylaluminum-triethylborane (TEA-TEB) as an engine igniter. [71] The booster stage has 9 engines, arranged in a configuration that SpaceX calls Octaweb. [72]
The Merlin 1D engine. The first stage is powered by three Falcon 9 derived cores, each equipped with nine Merlin 1D engines. The Falcon Heavy has a total sea-level thrust at liftoff of 22.82 MN (5,130,000 lbf), from the 27 Merlin 1D engines, while thrust rises to 24.68 MN (5,550,000 lbf) as the craft climbs out of the atmosphere.

In April 2017, SpaceX CEO Elon Musk said that Block 5 will feature 7–8% more thrust by uprating the engines (from 176,000 pounds-force (780,000 N) to 190,000 pounds-force (850,000 N) per engine). [14] Block 5 includes an improved flight control system for an optimized angle of attack on the descent, lowering landing fuel requirements.
In late 2001, Mueller began developing a liquid-fueled rocket engine in his garage and later moved his project to a friend's warehouse in 2002. [1] His design was the largest amateur liquid-fuel rocket engine, weighing 80 lb (36 kg) and producing 13,000 lbf (58 kN) of thrust. [1] His work caught the attention of Elon Musk, SpaceX founder. [7]
