A method of joining thermoplastic materials by rubbing the mating surfaces together while applying a large amount of pressure. Heat caused by the friction softens the material, and the pressure fuses the softened edges together.
Industry:Aviation
A method of joining two pieces of thermoplastic material. Butt fusion is done by heating the ends of the two pieces until they are in a molten state and forcing them together before they cool and harden.
Industry:Aviation
A method of keeping moisture from condensing on the windows of an aircraft operating in the cold air at high altitudes. Warm compressor bleed air is blown between the layers of transparent material of which the windows are made.
Industry:Aviation
A method of liquid cooling a reciprocating engine in which the coolant, normally water, is allowed to absorb enough heat that it boils, or changes into steam. The steam gives up this heat when it condenses back into a liquid.
Industry:Aviation
A method of locating a radio transmitter by using radio receivers equipped with directional antennas. The station to be located is received by two or more RDF stations, and the bearings (the direction from the receivers to the transmitter) are plotted on a chart. The transmitting antenna is located at the point the bearings from all of the RDF stations cross.
Industry:Aviation
A method of locking a shaft into a wheel or disk. A number of equally spaced parallel slots are cut lengthwise into the surface of a shaft. Matching slots are cut in the inside surface of the hole into which the shaft fits, and the splines prevent the shaft rotating in the hole.
Industry:Aviation
A method of machining large sheets of metal by chemically etching away part of the surface. The inside of the skins of some high-performance aircraft are etched to remove metal not needed for strength. Removing this metal by chemical milling reduces the weight of the aircraft.
Chemical milling produces a lightweight skin with all the needed strength and rigidity far more economically than can be done with conventional machining or by building up a skin with riveted-on stiffeners.
Industry:Aviation
A method of magnetic particle inspection in which the part is inspected while the magnetizing current is flowing either through the material or through a coil, or solenoid around the part.
Industry:Aviation
A method of magnetizing a part for magnetic particle inspection. Current flows through a solenoid, or coil, that encircles the part so the lines of magnetic flux pass lengthwise through it. Longitudinal magnetism makes it possible to detect faults that extend across the part.
Industry:Aviation
A method of magnetizing a part for magnetic particle inspection. Current is passed through the part, and the lines of magnetic flux surround it. Circular magnetization makes it possible to detect faults that extend lengthwise through the part.
