An air chamber inside a gas turbine engine that is used to absorb some of the thrust load produced by the rotating compressor.
Industry:Aviation
An air compressor driven by gears from the crankshaft of a reciprocating engine. Power is taken from the engine to drive the supercharger, but the increase in power produced by compressing the intake air more than compensates for the loss. Gear-driven superchargers are not as efficient as turbochargers, because the power used to drive a turbocharger would otherwise be wasted.
Industry:Aviation
An air compressor which supplies compressed air to pressurize the cabin of an aircraft.
Pressurization is needed when aircraft fly at high altitudes. If the cabin is not pressurized, the occupants must use supplemental oxygen.
Industry:Aviation
An air defense identification zone (ADIZ) over the coastal waters of Alaska.
Industry:Aviation
An air ducting system used in a multiengine turbojet airplane in which compressor bleed air from one engine can be directed to another engine where it can be used to operate its air starter.
Industry:Aviation
An air mass with characteristics developed over high latitudes, especially within the subpolar highs. Continental polar air (cP) has cold surface temperatures, low moisture content, and, especially in its source regions, great stability in its lower layers. It is shallow in comparison with Arctic air. Maritime polar (mP) air initially possesses similar properties to those of continental polar air, but as it passes over warmer water, it becomes unstable, with a higher moisture content.
Industry:Aviation
An air mass with characteristics developed over the low latitudes. Maritime tropical (mT) air, the principal type, is produced over the tropical and subtropical seas and is very warm and humid. Continental tropical (cT) air is produced over subtropical arid regions and is hot and very dry.
Industry:Aviation
An air pump used to increase the pressure of the air taken into the cylinders of a reciprocating engine. The amount of power a reciprocating engine can develop is determined by the mass, or weight, of the fuel-air mixture taken into the cylinders. By compressing the air before it enters the cylinders, a greater mass of air can be used, and more power can be developed by the engine.
Superchargers can be gear-driven from the engine, or they can be driven by a turbine spun by exhaust gases. Superchargers driven by exhaust gases are called turbochargers or turbosuperchargers.
Industry:Aviation
An air pump used to remove air from a container. There are two types of vacuum pumps: those that produce a very low absolute pressure (a high vacuum) with almost no flow of air, and those that produce less vacuum (a higher absolute pressure) but move a much larger volume of air.
Industry:Aviation
An air traffic activity level associated with the designed capacity for a sector or airport. The OALT considers dynamic changes in staffing, personnel experience levels, equipment outages, operational configurations, weather, traffic complexity, aircraft performance mixtures, transitioning flights, adjacent airspace, hand-off/point-out responsibilities, and other factors that may affect an air traffic operational position or system element.
The OALT is normally considered to be the total number of aircraft that any traffic functional position can accommodate for a defined period of time under a given set of circumstances.
