  2. Schlieren photography - Wikipedia

    en.wikipedia.org/wiki/Schlieren_photography

    Background-oriented schlieren technique (BOS [7]) relies on measuring or visualizing shifts in focused images. In these techniques, the background and the schlieren object (the distortion to be visualized) are both in focus and the distortion is detected because it moves part of the background image relative to its original position.

  3. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    The wind frame is a convenient frame to express the aerodynamic forces and moments acting on an aircraft. In particular, the net aerodynamic force can be divided into components along the wind frame axes, with the drag force in the −x w direction and the lift force in the −z w direction. Mnemonics to remember angle names

  4. Aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Aerodynamics

    Modern aerodynamics only dates back to the seventeenth century, but aerodynamic forces have been harnessed by humans for thousands of years in sailboats and windmills, [3] and images and stories of flight appear throughout recorded history, [4] such as the Ancient Greek legend of Icarus and Daedalus. [5]

  5. Flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Flight_dynamics

    Propulsive, aerodynamic, and gravitational force vectors acting on a space vehicle during launch. The forces acting on space vehicles are of three types: propulsive force (usually provided by the vehicle's engine thrust); gravitational force exerted by the Earth and other celestial bodies; and aerodynamic lift and drag (when flying in the atmosphere of the Earth or another body, such as Mars ...

  6. History of aerodynamics - Wikipedia

    en.wikipedia.org/wiki/History_of_aerodynamics

    Although the modern theory of aerodynamic science did not emerge until the 18th century, its foundations began to emerge in ancient times. The fundamental aerodynamics continuity assumption has its origins in Aristotle's Treatise on the Heavens, although Archimedes, working in the 3rd century BC, was the first person to formally assert that a fluid could be treated as a continuum.

  8. Starting vortex - Wikipedia

    en.wikipedia.org/wiki/Starting_vortex

    A starting vortex behind a wing profile, made visible by plotting pressure distribution in a CFD simulation.. In fluid dynamics, the starting vortex is a vortex which forms in the air adjacent to the trailing edge of an airfoil as it is accelerated from rest. [1]

  9. High-speed flight - Wikipedia

    en.wikipedia.org/wiki/High-speed_flight

    In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is immersed. At airspeeds below about 260 kn (480 km/h; 130 m/s; 300 mph), air can be considered incompressible in regards to an aircraft, in that, at a fixed altitude , its density remains nearly constant while its ...
