A device, either hand-held or installed in an aircraft, that directs a fire extinguishing agent onto a fire.
Industry:Aviation
A device, such as an electric arc chamber, that generates an extremely large amount of heat and changes neutral gases into plasma.
Industry:Aviation
A diagonal, load-bearing member of a Pratt truss wing. Antidrag wires run from the rear spar inboard, to the front spar outboard, and are crossed by the drag wires. Antidrag wires oppose the aerodynamic loads on the wing that try to move the tip of the wing forward.
Industry:Aviation
A diagram of a wiring or plumbing installation in which sketches of the actual component, rather than symbols, are used to represent components.
Industry:Aviation
A diagram of an electric or fluid power system in which the components are represented by symbols, rather than drawings or pictures of the actual devices. Schematic diagrams are used for troubleshooting.
Industry:Aviation
A diagram showing the relationship between the volume of a cylinder and the pressure during a cycle of engine operation.
Industry:Aviation
A diagram that uses special symbols connected by arrows or lines to indicate the sequence of step-by-step procedures that must be followed to accomplish a given task. Flow charts are used to design a computer program and to explain processes that take place in manufacturing.
Industry:Aviation
A diamond that is not of gem quality, but because of its hardness, is used as an industrial cutting tool.
Industry:Aviation
A dielectric (insulating) material that is permanently polarized. Electret is made by heating a material such as barium titanate ceramic or carnauba wax and holding it in a strong electric field as it cools. The electric field surrounding electret is much like the magnetic field surrounding a piece of magnetized steel.
Industry:Aviation
A dielectric (insulator) that, when an electric field is removed, returns to the circuit all the energy used to establish the field. A perfect dielectric has absolutely no conductivity — its resistance is infinite. The only known perfect dielectric is a vacuum.
