SpaceX CEO Elon Musk revealed that the Raptor 2 engine operates at 300 bar main pressure chamber meant for the Starship spacecraft for its upcoming missions. The new version of the Raptor beat the ...

The SpaceX Raptor engine has set a new record for the highest pressure in a record engine. The Russian RD-180 held the highest record pressure in its combustion chamber for decades. It had a pressure ...

The Raptor engine is made for reusability, not retirement. It’s designed to take off , land , and launch again with minimal work in between— a complete shift in how we think about access to space.

For a liquid-fueled rocket engine to work, you need to pump the fuel and oxidizer into the combustion chamber at the right quantity, pressure, and ratio. Handling this task is a turbopump, which ...

This turns the pump and spews almost every last bit into the combustion chamber, propelling the rocket with what Musk says is 99% efficiency, or the maximum allowed by physics as we know it today.

It's the same kind of mode of operation SpaceX is using for its Raptor engines. In a nutshell, such engines have propellant going through several combustion chambers, ...
