A solid-state component in which the flow of current between its emitter and collector is controlled by a much smaller flow of current into or out of its base. Bipolar transistors may be of either the NPN or PNP type.
Industry:Aviation
A solid-state electrical component that produces a voltage when it is exposed to light.
Industry:Aviation
A solution in which a solid is dissolved in a liquid until the liquid will hold no more. A supersaturated solution of salt and water has some salt crystals in the liquid. The amount of crystals depends upon the temperature of the solution. As the temperature decreases, more crystals precipitate out of the solution.
Industry:Aviation
A solution of potassium or sodium dichromate used to form a hard, airtight film on the surface of magnesium parts to prevent corrosion.
Industry:Aviation
A solution of salt (sodium chloride) and water, used as a quenching medium in the heat treatment of metal.
Steel parts quenched in brine are harder than parts quenched in either water or oil.
Industry:Aviation
A solvent mixed with a finishing material, such as lacquer, dope, or enamel, to reduce its viscosity so it can be sprayed.
Industry:Aviation
A solvent used to soften carbon deposits that have formed on metal surfaces. Carbon formed on engine parts because of the coking action of oil is hard and is baked onto the surface of the metal. It must be softened with a decarbonizer before it can be removed.
Some decarbonizers are used cold, and others are heated to make them act faster.
Industry:Aviation
A source of electrical energy for an aircraft that may be used for starting the engine and as auxiliary electrical power when the engine-driven generator is not operating.
Industry:Aviation
A source of high-voltage direct current needed for vacuum tubes. Vacuum tubes must have a high positive DC voltage on their plates and screen grids to pull electrons across the vacuum from the cathode. This high voltage is called B plus (B+) voltage.
Industry:Aviation
A source of light produced by an electric arc which is an intense and continuous spark. The arc is produced when electrons flow through ionized gases between two electrodes.
