A type of drilling tool in which a twist drill is held in a chuck mounted at an angle to the spindle of the drill motor. Angle drills are often used in aircraft sheet metal work to drill holes in locations where a normal drill cannot be used.
Industry:Aviation
A type of electric furnace used to melt metal. The metal is placed in a container lined with a material that can withstand extremely high temperatures, and a carbon rod is lowered to contact the metal. Electrical current is then forced to flow between the rod and the metal.
While current is flowing, the rod is slowly pulled away, and as it breaks contact, an intensely hot arc forms between the rod and the metal. This arc melts the metal.
Industry:Aviation
A type of electric motor whose stator windings are wound in a series of slots in the motor frame. A distributed pole motor is different from a salient pole motor whose field windings are wound around separate pole shoes that project inward from the frame toward the rotor.
Industry:Aviation
A type of electric motor-driven grinding wheel mounted on a pedestal, rather than on a bench.
Industry:Aviation
A type of electrical bus that allows all of the voltage-sensitive avionic equipment to be isolated from the rest of the aircraft electrical system when the engine is being started or when the ground-power unit is connected.
Industry:Aviation
A type of electrical cable made up of two insulated wires twisted together and enclosed in an outer insulation. The magnetic fields caused by current flowing in the two conductors of a twisted pair cancel each other and minimize the magnetic field radiating from the conductors.
Industry:Aviation
A type of electrical circuit in which some of the components are connected in series, and others are connected in parallel.
Industry:Aviation
A type of electrical circuit protection device that opens the alternator field circuit when the output circuit voltage drops below a specified low value.
Industry:Aviation
A type of electrical component, used to change alternating current into direct current. Drops of liquid mercury inside an evacuated glass tube are changed into mercury vapor by heat from a built-in filament. Mercury vapor can be ionized by a low voltage of one polarity, but it must have an extremely high voltage of the opposite polarity to ionize it. This makes it a good rectifier. Mercury rectifiers have a small voltage drop across them when they are conducting, and they are efficient conductors of large amounts of current in high-voltage circuits.
Industry:Aviation
A type of electrical connector used to carry a group of conductors through a bulkhead or panel. Feedthrough connectors do not have wires fastened to them, but rather they allow cables on both sides of the bulkhead to be connected through them.
Sealed feedthrough connectors carry circuits through the bulkheads of pressurized aircraft.
