The flame temperature of combustion in an aircraft refers to the temperature achieved during the combustion of fuel in the aircraft’s engine. This temperature is a critical parameter because it affects the efficiency of the engine and influences the performance of the aircraft. The flame temperature depends on factors such as the type of fuel used, the combustion process, and the engine design.
The adiabatic flame temperature Tadiabatic is an estimate of the maximum temperature reached during combustion when no heat is lost to the surroundings. The formula for adiabatic flame temperature is:
Where:
- Tadiabatic: Adiabatic flame temperature (in Kelvin).
- : Inlet air temperature (in Kelvin).
- : Fuel temperature (in Kelvin).
- : Specific heat at constant pressure (in J/(kg·K)).
- : Ratio of specific heats ().
- : Specific gas constant (in J/(kg·K)).
