The story so far: A Bengaluru-based space company, Astrobase Space Technologies, on Friday (August 7, 2026) unveiled India\u2019s first privately built 800 kN Full-Flow Staged Combustion (FFSC) LOX-Methane rocket engine named EVEREST.<\/p>\n
This makes India the fourth nation to have FFSC engine technology after Russia, USA and China.<\/p>\n
The FFSC rocket engines are very powerful engines where the propellant flows from the tank or the source to the rocket engine\u2019s combustion chamber. Staged combustion refers to combustion taking place in two stages wherein the fuel flows into the rocket engine from one side and the oxidiser from the other side.<\/p>\n
In the case of a staged combustion, the engine fuel is injected in relatively small quantities while oxidiser is on the higher side. The fuel and oxidiser which is burnt and gases generated out of it are used for turning the turbines connected to the pump.<\/p>\n
