What are drag wires?
: a member of a truss in the wing and also in the wing support of an airplane for sustaining the backward reaction due to the drag of the wing.
What is the purpose of drag and anti-drag wires?
Criss-crossed tension wires between the spars to form a truss to resist forces acting on the wing in the direction of the wing chord. The wire designed to resist the backward forces is called a drag wire; the anti-drag wire resists the forward forces in the chord direction.
How are replacement wires on aircraft are marked?
Placement of Identification Markings Added identification marker sleeves should be located so that ties, clamps, or supporting devices need not be removed to read the identification. The wire identification code must be printed to read horizontally from left to right) or vertically (from top to bottom).
What type of connector provide a pressure seal for maintaining pressurized areas?
Hermetic connectors provide a pressure seal for maintaining pressurized areas.
What is the angle of incidence in aviation?
On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle or setting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum drag, or where applicable, the longitudinal …
What is the standard slack will be given to a wire to prevent wire stress?
Wiring at terminal lugs or connectors should have sufficient slack to allow two reterminations without replacement of wires. This slack should be in addition to the drip loop and the allowance for movable equipment. Normally, wire groups or bundles should not exceed 1⁄2 inch deflection between support points.
What is the minimum bend radius for a wire bundle?
The minimum bending radius for all cables is eight times the overall cable diameter.
What is the maximum number of electric wire terminals that can be installed on one stud?
four terminals
Again, the ABYC recommends a maximum of four terminals on any one stud. There could in fact be more than four wires connected, as each terminal could have several small-gauge wires inserted into it. Your surveyor’s recommendation here is a good one, and this wiring should get sorted out.
What is used to attach connectors to wires?
Soldered connectors Many plug and socket connectors are attached to a wire or cable by soldering conductors to electrodes on the back of the connector. Soldered joints in connectors are robust and reliable if executed correctly, but are usually slower to make than crimped connections.
