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 such as an individual resistor or capacitor. Discrete components have been replaced in many modern circuits with integrated circuits in which a number of individual components are built into a single integrated circuit (IC) chip.
Industry:Aviation
A device supported in the air by displacing more than its weight of air. Balloons and dirigibles are examples of aerostats.
Industry:Aviation
A device sustained in the air by aerostatic lift. Balloons and dirigibles are examples of lighter-than-air aircraft made of materials that are heavier than air, but are filled with a gas (or with hot air) that is less dense than the surrounding air.
When a gas-filled aircraft displaces a greater weight of air than it weighs, aerostatic lift is produced, and the aircraft rises into the air.
Industry:Aviation
A device that allows a wheel to turn in one direction, but prevents its turning in the opposite direction.
The cam pawl, an eccentric that rides over the surface of a wheel, allows the wheel to turn in one direction, but when it tries to turn in the opposite direction, the cam wedges against the wheel and prevents its turning.
Industry:Aviation
A device that allows rotation of a wheel or handle in one direction, but prevents its turning in the opposite direction. A ratchet assembly consists of a toothed wheel and a pawl. The pawl is a lever that rides over the teeth when the wheel is turned in one direction, but engages the teeth to prevent the wheel turning in the opposite direction. Most ratchets have a method of reversing the pawl so the ratchet will work in either direction.
Industry:Aviation
A device that allows two transmitters to use a single antenna without either transmitter interfering with the other.
Industry:Aviation
A device that breaks a liquid into a fine spray to aid in its vaporization.
Industry:Aviation
A device that can be extended from the structure of an airplane to produce a large amount of parasite drag. Air brakes allow an airplane to increase its descent angle without building up an excessive amount of speed.
Also called dive brakes, air brakes differ from flaps in that they produce no useful lift.
Industry:Aviation
A device that can be used in an electrical circuit to get a high voltage. The secondary winding of a step-up transformer is connected to the primary winding of another step-up transformer.
As many transformers as are needed to get the required output voltage can be cascaded in this manner.
Industry:Aviation
A device that changes either variations in sound pressure into variations of electrical pressure (voltage), or variations in voltage into variations of sound pressure. Microphones and speakers are both examples of electroacoustic transducers.
