Dynamic pressure, denoted as , is a fundamental parameter in aerodynamics and aircraft design. It represents the kinetic energy per unit volume of a moving fluid (such as air) and is commonly used to describe the dynamic effects of air on an aircraft’s surfaces. Dynamic pressure is crucial in assessing aerodynamic forces and performance.
The formula for calculating dynamic pressure () is as follows:
- is the dynamic pressure (typically in pascals or pounds per square foot)
- is the air density (typically in kilograms per cubic meter or slugs per cubic foot).
- is the airspeed or velocity of the aircraft (typically in meters per second or feet per second).
