Shock Diamond

Shock Diamond

Shock diamonds (also known as Mach diamonds, Mach disks, Mach rings, doughnut tails or thrust diamonds) are a formation of standing wave patterns that appears in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet, or scramjet, when it is operated in an atmosphere. The diamonds are formed from a complex flow field and are visible due to the ignition of excess fuel. Mach diamonds (or disks) are named for Ernst Mach, the physicist who first described them.

Famous quotes containing the words shock and/or diamond:

    There are persons who, when they cease to shock us, cease to interest us.
    —F.H. (Francis Herbert)

    The lover never sees personal resemblances in his mistress to her kindred or to others. His friends find in her a likeness to her mother, or her sisters, or to persons not of her blood. The lover sees no resemblance except to summer evenings and diamond mornings, to rainbows and the song of birds.
    Ralph Waldo Emerson (1803–1882)
