Chamber Pressure
Chamber pressure is the pressure inside a rocket engine's combustion chamber, which is a key factor in determining its thrust.

TECHNICAL DEFINITION
Chamber pressure is the static pressure exerted by the hot combustion gases within the combustion chamber of a rocket engine, a critical parameter directly proportional to the thrust generated and indicative of engine performance and structural loads.
BACKGROUND
The RS-25, also known as the Space Shuttle Main Engine (SSME), is a liquid-fuel cryogenic rocket engine that was used on NASA's Space Shuttle and is used on the Space Launch System.
