The total energy liberated during the combustion of a fuel represents the amount of energy released when the fuel undergoes complete combustion. It is a critical parameter in aircraft design and is used to calculate the heat of combustion, which, in turn, affects engine performance, fuel efficiency, and other aspects of aircraft operation.The total energy liberated during combustion is typically expressed in terms of the energy content of the fuel.
The formula for calculating this energy can be defined as:
- Total Energy Liberated is the overall energy released during the combustion process, typically measured in joules (J) or British thermal units (BTU).
- Mass of Fuel Burned is the quantity of fuel consumed during combustion, measured in kilograms (kg) or pounds (lb).
- Heat of Combustion is the energy released per unit mass of fuel burned, often measured in joules per kilogram (J/kg) or British thermal units per pound (BTU/lb).
