A method of covering a material with a coating of metal. The metal to be used for the coating is melted and sprayed out with hot, high-velocity compressed air. Metal spraying is used to cover a steel part with aluminum to prevent corrosion, and it can also be used to cover a nonconductive material, such as wood or paper, with metal to make it electrically conductive.
Industry:Aviation
A method of covering an airplane by slipping a machine-sewed fabric envelope over the structure. After the envelope is slipped over the structure, the opening is hand-sewed closed, or the fabric is otherwise fastened to the structure. The fabric covering for the wings is laced to each of the ribs, and the fabric is shrunk.

A method of cutting metal or plastic with a hand file by moving the file crosswise over the work. Draw filing produces a very smooth finish.
Industry:Aviation
A method of cutting metal with a file in which the file is moved endwise over the work. Cross-filing is different from draw-filing, in which the file is moved sideways across the work.
Industry:Aviation
A method of damping vibration or oscillation by converting some of the vibrational energy into heat. Viscous damping is done by allowing the vibrating object to force a fluid, either a liquid or gas, through a small orifice. The amount of damping is determined by the viscosity of the fluid and the size of the orifice.
An aircraft nose wheel shimmy damper operates on the principle of viscous damping.
Industry:Aviation
A method of data transfer in which signals can travel in either direction.
Industry:Aviation
A method of decreasing aerodynamic drag caused by the turbulent flow of the boundary layer. Boundary-layer control can use either a high-velocity blast of air to blow the random-flowing air off the surface, or it can use a low pressure inside the structure to suck the boundary layer air off the surface through tiny holes or slots.
Industry:Aviation
A method of decreasing aerodynamic drag on the surface of an airplane wing. The boundary layer is the layer of air which flows in a random fashion directly over the surface of the wing.
Blown boundary layer control uses high-velocity air blown through ducts or jets to energize, or add energy to, the boundary layer. Energizing this air speeds it up and causes it to flow straight across the wing.
Industry:Aviation
A method of decreasing the speed of an airplane during its approach for landing. Airplanes without flaps can be slowed down and kept on a relatively straight flight path by alternately skidding the airplane to the left and then to the right, by using the rudder while keeping the wings level with the control stick or wheel. Side and forward slips are used more often than fishtailing for slowing an airplane.
Industry:Aviation
A method of depositing an extremely thin film of metal on a surface. A metallic vapor is formed by evaporating the metal in a high vacuum, or extremely low absolute pressure. This vapor is attracted to the surface to be metallized where it forms a microscopically thin coating.
