A type of circuit in either an electrical or a fluid power system in which all of the components are connected in such a way that they provide only one path from the source of current or fluid flow, through all of the components, and back to the source.
Industry:Aviation
A type of clamp used to hold material being turned on a lathe. The three jaws of a universal chuck are moved in and out at the same time by turning a chuck key. A universal chuck holds the work centered as the jaws are clamped tightly on the work.
Industry:Aviation
A type of clay or rock, the source of aluminum. To extract the aluminum, the bauxite is changed into alumina (aluminum oxide). Then, the alumina is reduced to metallic aluminum by an electrolytic process.
Industry:Aviation
A type of cloth made from yarn spun from fibers of the flax plant. Linen has been used for centuries as a fine cloth for clothing, and at one time was popular as a fabric for covering airplane structures.
Industry:Aviation
A type of clutch that couples a drive element with a driven element. When the drive element is being rotated, the driven element rotates with it. But when the driven element is being rotated by an outside force, the drive element does not turn.
Overrunning clutches are used in some types of aircraft engine starters. The starter rotates the engine through the clutch, but when the engine starts and turns faster than the starter motor, the clutch prevents the engine driving the starter.
Industry:Aviation
A type of clutch used to engage and disengage a component from a drive unit. The part of the clutch attached to the drive unit is a smooth internal cone, and the drive element of the clutch is made in the form of an external cone that mates exactly with the drive cone. Most cone clutches use a friction liner between the two surfaces.
Oil pressure applies a force that wedges the two cones tightly together to engage the clutch, and a spring disengages the clutch by forcing the cones apart when the oil pressure is released.
Industry:Aviation
A type of combustor used in some of the large turbojet and turbofan engines. It consists of individual cans into which the fuel is sprayed and ignited. These cans all mount on an annular duct through which the hot gases from the individual cans are collected and directed uniformly into the turbine.
Industry:Aviation
A type of communications in which signals can be sent in either direction, one direction at a time, but cannot be sent in both directions at the same time.
Industry:Aviation
A type of composite material in which the reinforcing fibers are encapsulated in an uncured resin. Prepreg must be kept refrigerated to prevent the resin curing before it is used. Prepreg materials are cut to size and shape and laid up with the correct ply orientation, and the entire component is cured with heat and pressure.
Industry:Aviation
A type of compressor used in gas turbine engines in which the air passes through the compressor in essentially a straight line, parallel to the axis of the compressor.
The compressor is made of a number of stages of rotating compressor blades between stages of stationary stator vanes. The compression ratio is determined by the number of stages of compression.
