An L-shaped metal extrusion having an enlarged, rounded edge that resembles a bulb on one of its legs. A bulb angle is used to provide stiffness to a structure, while keeping the weight to a minimum.
Industry:Aviation
An MS20426 aircraft solid rivet that has a countersunk head. The hole for the rivet is prepared by either countersinking or dimpling. When the rivet is driven, its head is flush with the surface of the metal. Flush rivets are used to produce an aerodynamically smooth surface.
Industry:Aviation
An object that has length, width, and depth. A cube, for example, is a three-dimensional object. A flat, or plane, surface on the other hand, has only length and width and is two-dimensional.
Industry:Aviation
An object that rotates in an orbit around a larger object. Today, man-made satellites rotate in orbits around the earth for the purposes of observation and communication.
Industry:Aviation
An obscuration to visibility caused by water droplets that are small enough to remain suspended in the air. Fog differs from drizzle in that it does not fall to the surface, and it differs from cloud only because it extends all the way down to the surface.
Industry:Aviation
An obstruction to visibility caused by fine dust or salt particles dispensed through a portion of the atmosphere. The particles are so small they cannot be felt or individually seen with the naked eye. Haze is distinguished from fog by its bluish or yellowish tinge.
Industry:Aviation
An obstruction to visibility caused by tiny ice crystals, rather than the tiny droplets of water that make up ordinary fog. Ice fog occurs at very low temperatures and may cause a halo.
Industry:Aviation
An off-route altitude which provides obstruction clearance with a 1,000-foot buffer in nonmountainous terrain areas and a 2,000-foot buffer in designated mountainous areas within the United States. This altitude may not provide signal coverage from ground-based navigational aids, air traffic control radar, or communications coverage.
Industry:Aviation
An oil analysis program in which a sample of oil is burned in an electric arc and an examination is made of the wavelength composition of the resulting light. Each chemical element in the oil, when burned, produces light containing a unique band of frequencies.
A computer analyzes the amount of each band of frequencies and prints out the number of parts of the element per million parts of the entire sample. SOAP can predict engine problems by warning the engine operator of an uncharacteristic increase in the amount of any of the elements in the oil.
