There are several standards for determining the weight of an aircraft used to calculate the thrust-to-weight ratio range. ... SpaceX Raptor 3 rocket engine [30] 1,525 ...
The engine's 150:1 thrust-to-weight ratio is the highest ever achieved for a rocket engine. [ 8 ] [ 9 ] The first flight of the Merlin 1D engine was also the maiden Falcon 9 v1.1 flight. [ 10 ]
In October 2012, SpaceX publicly announced concept work on a rocket engine that would be "several times as powerful as the Merlin 1 series of engines, and won't use Merlin's RP-1 fuel". [58] They indicated that the large engine was intended for a new SpaceX rocket, using multiple of these large engines could notionally launch payload masses of ...
Raptor is a family of rocket engines developed and manufactured by SpaceX. It is the third rocket engine in history designed with a full-flow staged combustion (FFSC) fuel cycle, and the first such engine to power a vehicle in flight. [15] The engine is powered by cryogenic liquid methane and liquid oxygen, a combination known as methalox.
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.

On 8 September 2005, SpaceX announced the development of the Falcon 9 rocket, which has nine Merlin engines in its first stage. [21] The design is an EELV-class vehicle, intended to compete with the Delta IV and the Atlas V, along with launchers of other nations as well. Both stages were designed for reuse.
