In flight mechanics, static temperature refers to the temperature of the air through which an aircraft is moving, without accounting for the effects of the aircraft’s motion. It is a key parameter in aerodynamics, influencing air density, and subsequently, lift and drag forces, as well as engine performance. The formula to calculate Static temperature as follows:
Where:
- is the static temperature in Kelvin.
- is the total temperature (including the effects of velocity and internal energy) at the stagnation point in Kelvin.
- is the heat capacity ratio or ratio of specific heats.
- M is the Mach Number.
