  2. Aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Aerodynamics

    For the continuum assumption to be valid, the mean free path length must be much smaller than the length scale of the application in question. For example, many aerodynamics applications deal with aircraft flying in atmospheric conditions, where the mean free path length is on the order of micrometers and where the body is orders of magnitude ...

  3. Aeroacoustics - Wikipedia

    en.wikipedia.org/wiki/Aeroacoustics

    Aeroacoustics is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces. Noise generation can also be associated with periodically varying flows. A notable example of this phenomenon is the Aeolian tones produced by wind blowing over fixed objects.

  4. Aeronautics - Wikipedia

    en.wikipedia.org/wiki/Aeronautics

    The science of aerodynamics deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. The study of aerodynamics falls broadly into three areas: Incompressible flow occurs where the air simply moves to avoid objects, typically at subsonic speeds below that of sound (Mach 1).

  5. Wind tunnel - Wikipedia

    en.wikipedia.org/wiki/Wind_tunnel

    A sample wind tunnel layout showing some typical features including a test section and control room, a machine for pumping air continuously through ducting, and a nozzle for setting the test airspeed. A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". [1]

  7. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    Lift is defined as the component of the aerodynamic force that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction.. A fluid flowing around the surface of a solid object applies a force on it.

  8. Ground effect (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Ground_effect_(aerodynamics)

    [9] Low winged aircraft are more affected by ground effect than high wing aircraft. [10] Due to the change in up-wash, down-wash, and wingtip vortices, there may be errors in the airspeed system while in ground effect due to changes in the local pressure at the static source. [9]
