  2. Normal shock tables - Wikipedia

    en.wikipedia.org/wiki/Normal_shock_tables

    In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number, the post-shock Mach number can be calculated along with the pressure, density, temperature, and stagnation pressure ratios. Such tables are useful ...

  3. Table of explosive detonation velocities - Wikipedia

    en.wikipedia.org/wiki/Table_of_explosive...

    Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough.

  4. Supercritical airfoil - Wikipedia

    en.wikipedia.org/wiki/Supercritical_airfoil

    Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).

  5. Shock wave - Wikipedia

    en.wikipedia.org/wiki/Shock_wave

    In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...

  6. Shock (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Shock_(mechanics)

    In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion.Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock i

  7. Oblique shock - Wikipedia

    en.wikipedia.org/wiki/Oblique_shock

    An oblique shock wave is a shock wave that, unlike a normal shock, is inclined with respect to the direction of incoming air. It occurs when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. [1] The upstream streamlines are uniformly deflected after the shock

  8. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    (In the case of a sharp object, there is no air between the nose and the shock wave: the shock wave starts from the nose.) As the Mach number increases, so does the strength of the shock wave and the Mach cone becomes increasingly narrow. As the fluid flow crosses the shock wave, its speed is reduced and temperature, pressure, and density increase.

  9. Transonic - Wikipedia

    en.wikipedia.org/wiki/Transonic

    Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
