A special type of wire-wound resistor used in electrical circuits.
A bifiliar resistor is wound of wire that is doubled back on itself to decrease the inductance in the resistor.
Industry:Aviation
A special type of wrench used to turn ring-shaped nuts. Thin, ring-shaped nuts are used on cylinders and rods as mechanical stops and locking nuts. These nuts are turned with a pin spanner whose pins fit into small holes in the outer circumference of the nut.
Industry:Aviation
A special wheel with notched teeth on its periphery. Gears transmit power from one shaft to another without slippage by meshing the teeth of the gear on one shaft with the teeth of the gear on the other. Gears are used to reverse the direction of shaft rotation and to gain mechanical advantage.
Industry:Aviation
A special work surface used with certain types of metal-machining tools. An electromagnetic force holds the material being machined tightly to the surface.
Industry:Aviation
A specialist in one of the technical fields. In research and development, technicians often assist engineers. The engineer’s knowledge of the theory behind the project is usually greater than that of the technician, but the technician usually has a more practical approach and is able to build the things the engineer designs.
Industry:Aviation
A specialized agency of the United Nations whose objective is to develop the principles and techniques of international air navigation and to foster planning and development of international civil air transport. The term ICAO is normally pronounced as a single word (eye-kay-o), rather than using the entire name or the initials.
Industry:Aviation
A specially designed viscosimeter, or cup for measuring the viscosity of a liquid. The Zahn cup is filled with the liquid whose viscosity is to be measured. A specially calibrated hole in the bottom of the cup is opened, and the time needed for the liquid to flow from the cup is measured. The number of seconds between the start of the flow and the time at which the first break in the flow occurs relates to the viscosity of the liquid.
Industry:Aviation
A specially shaped duct, or tube, used to carry fuel away from the aircraft when it is dumped from the fuel tanks.
Some large aircraft are permitted to take off with a greater weight than they are allowed to have when they land. However, if such an aircraft must make an emergency landing before it has burned off enough fuel to reduce its weight to its legal landing weight, it must dump enough fuel to get rid of this excess weight. The dump chute is designed to carry the fuel away from the aircraft so it will not be ignited by the engine exhaust or by static electricity.
Industry:Aviation
A specially shaped piston used in an aircraft reciprocating engine. The piston is not round, but is ground in such a way that its diameter parallel to the wrist pin is slightly smaller than its diameter perpendicular to the pin.
The mass of metal used in the wrist pin boss, the enlarged area around the wrist pin hole, expands when it is heated, and when the piston is at its operating temperature, it has expanded until it is perfectly round.
Industry:Aviation
A specially shaped restriction in a tube designed to speed up the flow of fluid passing through it. According to Bernoulli’s principle, any time a fluid is speeded up without losing or gaining any energy from the outside, the pressure of the fluid decreases.
Venturis are used in carburetors and in many types of fluid control devices to produce a pressure drop proportional to the speed of the fluid passing through them.
