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 device that uses electrical power. A load converts electrical energy into some other form of energy: mechanical, heat, light, or chemical.
Industry:Aviation
A device that warns the flight crew of the presence of smoke in cargo and/or baggage compartments. Some smoke detectors are of the visual type, others are photoelectric or ionization devices.
Industry:Aviation
A device used for mixing paints which shows the primary colors and the various colors that can be made by mixing them. A color wheel helps visualize the results you will get when you mix different colors of paint.
Industry:Aviation
A device used for training or research that duplicates a piece of complex equipment. Flight simulators duplicate the cockpit of an airplane. All of the controls and instruments are connected to a computer that gives the operator the feel and the indications that would exist under actual flight conditions in a real aircraft.
Emergency and unusual conditions can be simulated and practiced in the simulator far more safely and economically than can be done in the real aircraft.
Industry:Aviation
A device used in a hydraulic system to move fluid.
Most hand pumps are of the piston type, in which movement of the pump lever, or handle, moves a piston inside the pump.
Some hand pumps are single-acting, which means that they move fluid only during one stroke of the handle. No fluid is moved during the return stroke. Other hand pumps are double-acting, which means that they move fluid during both strokes of the handle.
Most aircraft hydraulic systems that use an engine-driven or electric motor-driven hydraulic pump have a hand pump as a backup in case the power pump fails.
Industry:Aviation
A device used to allow very fine adjustments or very small measurements to be made. A vernier coupling, for example, has two sets of splines, or teeth. One set has 35 teeth and the other set has 36 teeth. When the coupling is moved ahead one tooth on the 35-tooth side, it moves ahead 10.285 degrees (360 ÷ 35 = 10.285). When it is moved back one tooth on the 36-tooth side, it moves back 10 degrees (360 ÷ 36 = 10).
By moving the coupling ahead one tooth on the 35-tooth side and back one tooth on the 36-tooth side, the shafts joined by the coupling have been moved by an amount of only 0.285 degree.
Industry:Aviation
A device used to bleed an accumulated static electrical charge off an aircraft control surface and discharge it into the air. The wick is made of graphite-impregnated cotton fibers, enclosed in a plastic tube. One end of the wick is electrically connected to the trailing edge of a control surface, and the other end of the fibers are spread out of the end of the tube so the hundreds of fiber ends stick out into the air.
As the airplane flies through the air, static electricity builds up on the control surfaces, travels through the static wicks, and discharges into the air from the tips of the cotton fibers.
Industry:Aviation
A device used to connect a motor to a mechanical load. A plate or cone on the load is driven by a mating device on the motor. A lining made of a material that causes a good deal of friction separates the two surfaces, and a spring forces the surfaces and lining tightly together, allowing the motor to drive the load. The spring force can be released to disconnect the motor from the load.
Industry:Aviation
A device used to dampen vibrations or oscillations or to bring a vibrating body to a stop with a minimum of oscillations.
Industry:Aviation
A device used to exchange heat from one medium to another. Radiators, condensers, and evaporators are all examples of heat exchangers. Heat always moves from the object or medium having the greatest level of heat energy to a medium or object having a lower level.
Air-to-air, air-to-liquid, liquid-to-air, and liquid-to-liquid heat exchangers are commonly used with aircraft engines.
