Prandtl–Glauert singularity — F/A 18 with vapor cone The Prandtl–Glauert singularity is the prediction by the Prandtl–Glauert transformation that infinite pressure conditions would be experienced by an aircraft as it approaches the speed of sound. Because it is invalid to… … Wikipedia
Prandtl–Glauert transformation — The Prandtl–Glauert transformation or Prandtl–Glauert rule (also Prandtl–Glauert–Ackeret rule) is an approximation function which allows to compare aerodynamical processes occurring at different Mach numbers. Mathematical expression Even in… … Wikipedia
Compressible flow — is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number (the ratio of the flow… … Wikipedia
Lorentz transformation — A visualisation of the Lorentz transformation (full animation). Only one space coordinate is considered. The thin solid lines crossing at right angles depict the time and distance coordinates of an observer at rest with respect to that frame; the … Wikipedia

Max Q — For other uses, see Max Q (disambiguation). In aerospace engineering, the maximum dynamic pressure, often referred to as maximum Q or max Q, is the point at which aerodynamic stress on a vehicle in atmospheric flight is maximized. It is an… … Wikipedia
Underwater explosion — An underwater explosion, also known as an UNDEX, is an explosion beneath the surface of water. The type of explosion may be chemical or nuclear. They are categorized in accordance with their depth beneath the water s surface, because this has a… … Wikipedia
Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… … Wikipedia
Vorticidad — La figura muestra como se conserva la vorticidad si no hay viscosidad: si inicialmente era nula, cualquier variación encuentra en algún lado su variación opuesta. La vorticidad es una magnitud física empleada en mecánica de fluidos y en el mundo… … Wikipedia Español
