Combustion Efficiency
Combustion efficiency measures how effectively the fuel and oxidizer inside an engine's combustor burn to release their chemical energy as heat, compared to the theoretical maximum possible.
TECHNICAL DEFINITION
Combustion efficiency quantifies the ratio of actual heat released during the combustion of a fuel-oxidizer mixture within an aerospace propulsion system's combustor to the ideal, theoretical maximum heat release, indicating the completeness of combustion and directly impacting propulsive performance and specific fuel consumption.
BACKGROUND
The staged combustion cycle is a power cycle of a bipropellant rocket engine. In the staged combustion cycle, propellant flows through multiple combustion chambers, and is thus combusted in stages. The main advantage relative to other rocket engine power cycles is high fuel efficiency, measured through specific impulse, while its main disadvantage is engineering complexity.
