Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
A thin sheet metal separator that keeps the rollers or balls in an antifriction bearing evenly spaced around the races. The bearing cage should never touch either of the bearing races.
Industry:Aviation
A thin sheet metal shroud that wraps around the exhaust stack or the muffler of a reciprocating engine to pick up heat. Ventilating air blows through the muff and carries the heat it picks up into the cabin.
Industry:Aviation
A thin sheet of wood “peeled” from a log with a knife held against the log as it is rotated in the cutter. Veneer is used for making plywood. Several sheets of veneer are glued together, with the grain of each sheet placed at 45° or 90° to the grain of the sheets next to it.
Industry:Aviation
A thin slab of quartz, used to control the frequency of an electronic oscillator. A quartz crystal vibrates at its natural resonant frequency when it is excited with a pulse of electrical energy. As the crystal vibrates, it produces an alternating current whose frequency is determined by the physical dimensions of the crystal.
Industry:Aviation
A thin slice of silicon or germanium used as the substrate on which the components of an integrated circuit chip are formed. A wafer is also called a slice.
Industry:Aviation
A thin square of quartz or Rochelle salt that has the characteristic of producing a voltage across its opposite faces when it is physically distorted. The physical resonant frequency of the crystal makes it useful as a component in an oscillator to maintain a constant electrical frequency. When the crystal is shocked with a pulse of electrical energy, it vibrates at its resonant frequency. As it vibrates, it produces a voltage across its faces that varies at the same frequency as the crystal vibrates.
Industry:Aviation
A thin stream of electrons all moving in the same direction under the influence of electrical or magnetic fields. Electron beams may be focused and directed by these fields.
When an electron beam strikes certain phosphors, electroluminescence is produced and the phosphor glows. This is the way the image is formed on a television screen and on the face of a cathode-ray tube.
Industry:Aviation
A thin, flexible material made by treating the outside membrane of the large intestine of cattle. Goldbeater’s skin is used to separate sheets of gold foil as they are being hammered (beaten) until they are thinned into gold leaf. Many thousands of goldbeater’s skins were joined together to form the gas bags that held the lifting gas for the huge lighter-than-air dirigibles and Zeppelins.
Industry:Aviation
A thin, sharp edge on a piece of material, left as the material is worn away by abrasion.
