A cone with its point cut off in such a way that its top is parallel with its base.
Industry:Aviation
A connection in an electrical circuit which has an excessive amount of resistance. High-resistance connections are caused by corrosion, loose fasteners, and cold-solder joints.
Industry:Aviation
A connection inside a piece of electrical equipment between a metal part that does not carry current and the earth ground. Equipment ground is carried out of the equipment through a green wire connected to the round pin in the standard three-pin electrical plug.
The function of equipment ground is to reduce the possibility of electrical shock.
Industry:Aviation
A connector used to fasten a conductor to an electrical test panel. Most binding posts have an insulated nut that can be turned with the fingers to grip the wire. Some binding posts have, in addition to the nut, holes for a banana plug.
Industry:Aviation
A connector, made in the shape of the letter T, for joining either rigid or flexible fluid lines.
Industry:Aviation
A constant which, when divided into a moment, results in an index. Reduction factors of 100, 1,000, and 10,000 are used to simplify weight and balance computations.
Industry:Aviation
A constant-displacement fluid pump that uses sliding vanes to move fluid through the pump. An eccentrically mounted shaft is turned inside a circular housing that has an intake port on one side and an outlet port on the other. Flat vanes are free to slide back and forth through slots in the shaft as it turns.
As the shaft turns, the volume of the chamber connected to the intake port increases and pulls fluid into the pump. This fluid is carried around the inside of the pump until it reaches a point connected to the outlet port. At this point, the vanes sliding through the shaft decrease the volume of the chamber, and fluid is forced out of the pump. Vane-type pumps move a comparatively large volume of fluid, but produce a relatively low pressure and are used as fuel pumps and low-pressure air pumps.
Industry:Aviation
A constant-voltage charge given to a partially discharged storage battery for a short period of time.
Industry:Aviation
A constant-voltage charge given to dry-charged batteries to get them ready for installation. Most lead-acid batteries are shipped from the manufacturer in a dry-charged state. The battery was charged at the factory, the electrolyte was drained, and the cells were sealed.
When the battery is ready to be put into service, electrolyte having the proper specific gravity is poured into the cells, and the battery is given a constant-voltage freshening charge. The battery is considered ready for service when the specific gravity of the electrolyte does not change in three hours of charging.
Industry:Aviation
A constant-volume cycle of energy transformation that has separate strokes for intake, compression, power, and exhaust.
