// PROPULSION SYSTEMS AND ENGINE TECHNOLOGY TERM
Chamber Pressure
Chamber pressure is the pressure inside the combustion chamber of a rocket or jet engine, where propellants burn to produce hot gases. This high pressure is what forces the exhaust gases out through the nozzle, creating thrust.
TECHNICAL DEFINITION
Chamber pressure (Pc) denotes the absolute thermodynamic pressure within the combustion chamber of a rocket or jet engine, arising directly from the energetic combustion of propellants. This fundamental performance metric is critical for determining exhaust velocity, specific impulse, and overall engine thrust, influencing design, material selection, and operational efficiency.
BACKGROUND
The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed the combustion chamber pressure.
