The “Energy Input from Fuel” in aircraft design refers to the total energy released by the combustion of fuel in the aircraft’s engines. This energy input is crucial for calculating various engine and aircraft performance parameters, including thermal efficiency.
The formula for the energy input from fuel can be defined as:
- Energy Input from Fuel is the total energy released by burning the fuel, typically measured in joules (J) or British thermal units (BTU).
- Mass of Fuel Burned is the amount of fuel consumed during the combustion process, measured in kilograms (kg) or pounds (lb).
- Heat of Combustion is the energy released per unit mass of fuel burned, measured in joules per kilogram (J/kg) or British thermal units per pound (BTU/lb).
