In flight mechanics, the dynamic pressure is a fundamental concept used to characterize the energy or pressure associated with the motion of a fluid (such as air) in which an object (such as an aircraft) is moving. It is a crucial parameter in aerodynamics and is denoted by the symbol “q.”
- q is the dynamic pressure (in pascal or pounds per square foot).
- ρ is the air density (in kg/m³ or slugs/ft³) at the current altitude.
- V is the true airspeed of the aircraft (in m/s or ft/s).
