A hydrocarbon compound in which one or more of the hydrogen atoms have been replaced with an atom of one of the halogen elements, such as fluorine, chlorine, or bromine.
Industry:Aviation
A hydrocarbon fuel (gasoline) manufactured by heating crude petroleum products under pressure, usually in the presence of a catalyst. The heavier hydrocarbons in the crude oil are broken down by the cracking process into products that are distilled into gasoline.
Industry:Aviation
A hydrocarbon fuel used in a compression-ignition engine. Diesel fuel, obtained by fractional distillation of crude oil, is the fraction that distills off just after kerosine.
Industry:Aviation
A hydrocarbon, C7H16, that has a very low critical pressure and temperature. Normal heptane is used as the low reference in measuring the anti-detonation characteristics of aviation gasoline.
Industry:Aviation
A hydrofoil mounted below the hull of a flying boat. As the flying boat begins to move through the water, hydrodynamic lift produced by the hydro-ski lifts the hull out of the water. When the hull is out of the water, the drag is decreased, and the flying boat can quickly accelerate to takeoff speed.
Industry:Aviation
A jet-propelled aircraft that has three engines. The Boeing 727, the McDonnell-Douglas MD-11, and Lockheed L-1011 are all trijet airplanes.
Industry:Aviation
A joint in a wood structure in which the ends to be joined are cut in a long taper, normally 12:1, and fastened together by gluing. A glued scarf joint makes a strong splice, because the joint is made along the side of the wood fibers rather than along their ends.
Industry:Aviation
A joint in the structure of an aircraft formed when two subassemblies are removed from their jigs and joined together to form a single unit.
Industry:Aviation
A joint in which the two sheets of metal are riveted together. The rivet is subjected to only a single shear load as the sheets try to slide past one another.
Industry:Aviation
A joint or connection made between two pieces of wood by an adhesive, or glue, rather than any type of mechanical fastener. The wood is prepared by shaping it so the grains in the two pieces are parallel, and the surfaces to be glued are perfectly smooth and clean. The glue is spread evenly over either one or both surfaces, and the surfaces are pressed together and held by clamps until the glue dries. A correctly made glue joint is stronger than the wood itself.
