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 small steel cylinder containing aviators breathing oxygen. The walk-around bottle is fastened to the flight suit and attached to the oxygen mask to supply the aviator with oxygen as he or she walks around the aircraft.
When the aviator is at his or her regular duty station, the walk-around bottle is disconnected, and the oxygen mask is plugged into the built-in oxygen system.
Industry:Aviation
A small strip of corrugated steel ground on one edge to form a series of sharp points. Corrugated fasteners are driven into butt joints in wood to fasten the pieces together.
Industry:Aviation
A small strip of resistance wire mounted inside a tubular cathode in an electron tube. Low-voltage AC flowing through the heater causes it to get red-hot. This heats the cathode enough for it to emit, or give off, electrons.
Industry:Aviation
A small strut that connects the center of the main wing struts of a strut-braced monoplane to the wing spar. A jury strut stiffens the main struts to prevent their vibrating.
Industry:Aviation
A small system inside a larger system. Each subsystem has a job it must perform for the main system to operate properly.
Industry:Aviation
A small- to medium-size digital computer. There is no clear-cut distinction between a small minicomputer and one of the larger microcomputers, but generally speaking, a minicomputer is faster and can be expanded more than a microcomputer.
Industry:Aviation
A small transformer-rectifier connected across a storage battery to charge it at a slow rate. Trickle chargers are limited to a small amount of current by an internal circuit breaker that opens the primary circuit if the battery requires too much current.
Industry:Aviation
A small triangular metal strip installed along the leading edge of an airplane wing near the root. Many airplane wings begin to stall near the tip, in the area ahead of the ailerons. When this portion of the wing stalls, the pilot no longer has good control of the aircraft.
To allow adequate control throughout the stall, the small stall strips force the roots of the wing to stall before the tips. When the wing roots stall, the nose of the aircraft drops, and the aircraft recovers from the stall with complete control throughout.
Industry:Aviation
A small tube that connects the burner cans in a multiple-can combustor. Crossover tubes carry flame from one can to the other when the engine is being started.
Industry:Aviation
A small turbine in an air-cycle cooling system that extracts energy from compressed air as it drives a compressor.
Bleed air containing a large amount of energy is taken from the turbine-engine compressor. This hot air passes through a primary heat exchanger where it gives up some of its energy. It is then taken into a compressor driven by the expansion turbine. Here its pressure and temperature are both increased. This air then passes through a secondary heat exchanger where it gives up more of its energy and its temperature is dropped. From here it flows into the expansion turbine that drives the compressor, using up much of its remaining energy.
After leaving the turbine, it expands into the air conditioning ducts. Having lost most of its energy through the heat exchangers and the expansion turbine, the air is now cold.
