SpaceX Raptor Engine Is Completely Dominated Over Blue Origin BE-4 Engine…

Spacex and blue origin have been competing with each other, for many spacecrafts and commercial contracts. Both the companies are developing there next generation rocket, But spacex is the leading space company has made many rocket engines, since its launch in 2002.
Previous year spacex completed its 100th raptor engine, this extraordinary milestone was achieved in just 29 months, a little over two years blue origin’s rocket engine’s development started, work on the be 4 engine since 2011.
Importantly, they said the be4 would be ready for flight by 2017, but at this very moment blue origin’s powerful be4 engine is more than four years late. The first flight test of the new engine is now expected no earlier than 2022, on the vulcan rocket, this is a big problem and we need to talk about it.

Spacex’s raptor engine the king of rocket engines, let’s compare spacex’s open cycle merlin engine, that powers their falcon 9 and falcon heavy rockets. Spacex’s full flow staged combustion cycle raptor engine, blue origin’s closed cycle, oxygen-rich methane-powered, be4 engine.
Which runs on hydrogen, the sls is great, but what’s maybe just as important, when designing a rocket is the thrust to weight ratio, or how heavy the engine is compared to how much thrust it produces. First how has be4 gone through almost a decade of failure, this was their first engine to combust liquid oxygen, and liquefied natural gas propellants.
It was initially planned for the engine to be used exclusively, on a blue origin proprietary launch vehicle new glenn, the company’s first orbital rocket. However it was announced in 2014, that the engine would also be used on the united launch alliance, vulcan centaur launch vehicle.
