glue. A general term used for an adhesive material. glue joint (wood aircraft construction). 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. Glyptal. The registered trade name for an insulating varnish used to insulate certain types of electrical machinery. go, no-go gage. A type of measuring device used to determine whether or not the dimensions of an object being measured are within allowable limits. A go, no-go gage can be used to determine if a hole is of the correct size. If the hole is at least as large as the minimum diameter allowed, the “go” part of the gage will fit into it, and if it is no larger than the maximum diameter allowed, the “no-go” part of the gage will not fit into it. “Go ahead” (air traffic control). The phrase used by air traffic controllers meaning “proceed with your message.” This phrase is not to be used for any other purpose. “Go around” (air traffic control). Instructions for a pilot to abandon his approach to landing. go-around power or thrust setting. The maximum allowable inflight power or thrust setting identified in the performance data. gold. A soft, yellow, heavy, corrosion-resistant chemical element. Gold’s symbol is Au, its atomic number is 79, and its atomic weight is 196.967. Gold is a good thermal and electrical conductor, and because of its resistance to corrosion, it is often plated onto critical electrical contacts and slip rings. goldbeater’s skin. A thin, flexible material made by treating the outside membrane of the large intestine of cattle. Goldbeater’s skin is used to separate sheets of gold foil as they are being hammered (beaten) until they are thinned into gold leaf. Many thousands of goldbeater’s skins were joined together to form the gas bags that held the lifting gas for the huge lighter-than-air dirigibles and Zeppelins. gold leaf. Pure gold that has been rolled or beaten into extremely thin sheets. Gold leaf is usually about one microinch (1 x 10-6 inch) thick. Gold foil is similar to gold leaf, but is thicker. goniometer. An instrument used to measure angles. The goniometer used in an automatic direction finder (ADF) uses the output of a fixed loop antenna to sense the angle between a fixed reference, usually the nose of the aircraft, and the direction from which the radio signal is being received. An electronic goniometer measures the angle by comparing radio signals picked up on a nondirectional antenna with signals picked up on a directional antenna. gore (parachute component). A single triangular-shaped panel in the canopy of a parachute. The canopy is made by sewing the gores together to form a large circular canopy. Shroud lines are sewed along the seams that join the gores. |
