  2. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    Dynamic pressure is one of the terms of Bernoulli's equation, which can be derived from the conservation of energy for a fluid in motion. [1] At a stagnation point the dynamic pressure is equal to the difference between the stagnation pressure and the static pressure, so the dynamic pressure in a flow field can be measured at a stagnation point ...

  3. Max q - Wikipedia

    en.wikipedia.org/wiki/Max_q

    Chart of dynamic pressure during the Mercury-Redstone 4 mission. Max q occurs 90 seconds after launch, at 600 lb/sq ft (290 hPa).. The max q, or maximum dynamic pressure, condition is the point when an aerospace vehicle's atmospheric flight reaches the maximum difference between the fluid dynamics total pressure and the ambient static pressure.

  4. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    The aerodynamic efficiency has a maximum value, E max, respect to C L where the tangent line from the coordinate origin touches the drag coefficient equation plot. The drag coefficient, C D, can be decomposed in two ways. First typical decomposition separates pressure and friction effects:

  5. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    q, the dynamic pressure, is equal to 1/2 ρv 2, where ρ is atmospheric density, modeled for Earth as a function of altitude in the International Standard Atmosphere (using an assumed temperature distribution, hydrostatic pressure variation, and the ideal gas law); and

  6. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Many authors refer to the pressure p as static pressure to distinguish it from total pressure p 0 and dynamic pressure q. In Aerodynamics, L.J. Clancy writes: "To distinguish it from the total and dynamic pressures, the actual pressure of the fluid, which is associated not with its motion but with its state, is often referred to as the static ...

  7. Impact pressure - Wikipedia

    en.wikipedia.org/wiki/Impact_pressure

    In compressible fluid dynamics, impact pressure (dynamic pressure) is the difference between total pressure (also known as pitot pressure or stagnation pressure) and static pressure. [ 1 ] [ 2 ] In aerodynamics notation, this quantity is denoted as q c {\displaystyle q_{c}} or Q c {\displaystyle Q_{c}} .

  8. Equivalent airspeed - Wikipedia

    en.wikipedia.org/wiki/Equivalent_airspeed

    where a 0 is 1,225 km/h (661.45 kn) (the standard speed of sound at 15 °C), M is the Mach number, P is static pressure, and P 0 is standard sea level pressure (1013.25 hPa). Combining the above with the expression for Mach number gives EAS as a function of impact pressure and static pressure (valid for subsonic flow):

  9. Aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Aerodynamics

    Internal aerodynamics is the study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a jet engine or through an air conditioning pipe. Aerodynamic problems can also be classified according to whether the flow speed is below, near or above the speed of sound.
