The Merlin 1B rocket engine was an upgraded version of the Merlin 1A engine. The turbopump upgrades were handled by Barber-Nichols, Inc. for SpaceX. [ 10 ] It was intended for Falcon 1 launch vehicles, capable of producing 380 kN (85,000 lbf) of thrust at sea level and 420 kN (95,000 lbf) in vacuum, and performing with a specific impulse of 261 ...
Merlin 1B had a somewhat more powerful turbo-pump, and generated more thrust, but was never flown on a flight vehicle before SpaceX's move to the Merlin 1C. Merlin 1D rocket engines on a Falcon 9 v1.1 launch vehicle in SLC-40 hangar, April 2014. The Merlin 1C was the first in the family to use a regeneratively-cooled nozzle and combustion chamber.

[8] [9] It is powered by Merlin 1D engines burning rocket-grade kerosene and liquid oxygen (LOX). The main changes from Block 3 (the original Falcon 9 Full Thrust) to Block 5 are higher-thrust engines and improvements to the landing legs along with numerous other small changes to streamline recovery and re-use of first-stage boosters and ...
As Vice President of Propulsion Engineering and subsequently CTO of Propulsion at SpaceX, Mueller led the team that developed the Merlin 1A and Kestrel engines for the Falcon 1, the first liquid fueled orbital rocket launched by a private company; the Merlin 1C, Merlin 1D and MVac engines for the early iterations of the Falcon 9 launch vehicle ...
In January of that year, SpaceX first flew a "Falcon 9 rocket with a 3D-printed Main Oxidizer Valve (MOV) body in one of the nine Merlin 1D engines". The valve is used to control flow of cryogenic liquid oxygen to the engine in a high-pressure, low-temperature, high-vibration physical environment. [5]
Propulsion for the rocket was planned to be provided by four Merlin 1D rocket engines, engines that were also to be used in the Falcon 9 v1.1 beginning in 2013, and also on the Falcon Heavy in 2014. Its first flight was notionally planned for 2016.
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]
