Flameout approaches terminate in the type of approach requested by the pilot (normally full stop). flame resistant. 14 CFR Part 1: “Not susceptible to combustion to the point of propagating a flame, beyond safe limits, after the ignition source is removed.” flame spraying. A process in which molten metal is deposited on a surface. A wire of the metal to be deposited is fed into an oxy-acetylene flame and melted. The molten metal is blown by a stream of high-pressure air onto the surface to be coated. Pure aluminum can be sprayed onto steel to prevent corrosion, and metal can be sprayed onto an insulating material to make the surface electrically conductive. flame tubes (turbine engine component). Small-diameter metal tubes that connect can-type combustors to carry the ignition flame to all of the combustion chambers. flammable. Easily ignited. Flammable replaces the older term inflammable which can be misinterpreted to mean not flammable. 14 CFR Part 1: “With respect to a fluid or gas, means susceptible to igniting readily or to exploding.” flammable liquid. A liquid that gives off combustible vapors (vapors that are easily ignited). Gasoline is an example of a flammable liquid. flange. A ridge that protrudes from a device and is used for attaching something to the device, or for connecting two objects together. The propeller shaft of most modern aircraft engines is fitted with a flange on which the propeller mounts. The end of the propeller shaft is formed into a flat plate (the flange) whose face is perpendicular the propeller shaft. The propeller is held on this flange with high-strength steel bolts. flap (helicopter rotor blade movement). Up-and-down movement of the tip of a helicopter rotor blade. |
