A heavy-duty electrical resistor, used to dissipate large amounts of electrical energy. Load banks are used to discharge storage batteries for servicing them and to dissipate large amounts of current when loading a generator as is done with a reciprocating engine dynamometer.
Industry:Aviation
A heavy-duty, multiple-disk brake used on large, high-speed aircraft. Stators, surfaced with a material that retains its friction characteristics at high temperatures, are keyed to the axle. Rotors, keyed into the wheels, rotate between each pair of stators. The rotor disks are made in segments to aid in dissipation of heat and to prevent their warping.
Industry:Aviation
A heavy-duty, remotely operated switch used to control electrical circuits carrying large amounts of current.
Industry:Aviation
A helical gear mounted on a shaft and meshed with a spur gear whose teeth are cut at an angle to its face. A worm gear is an irreversible type of mechanism. Rotating the shaft on which the worm gear is mounted rotates the spur gear, but the worm gear locks the spur gear so its shaft cannot be rotated.
Industry:Aviation
A helicopter hovering in ground effect (IGE) is in flight, but it is not moving over the ground, and it is flying at a height equal to or less than the span of its rotor above the surface. A helicopter can hover in ground effect at a higher density altitude than it can hover out of ground effect.
Industry:Aviation
A helicopter hovering out of ground effect (OGE) is in flight, but it is not moving over the ground, and it is flying at a height above the ground greater than the span of its rotor.
Industry:Aviation
A helicopter rotor attached in its hub so its only freedom of movement is that of changing the blade pitch angle. The blades of a rigid rotor have no hinges that allow them to flap or drag.
Industry:Aviation
A helicopter rotor in which each blade is connected to the rotor hub in such a way that it is free to move up and down (flap), move back and forth in its plane of rotation (drag), and change its pitch angle (feather).
Industry:Aviation
A helicopter rotor whose blades are attached to the hub in such a way that they are free to flap, drag, and feather.
Industry:Aviation
A helicopter rotor with its center of gravity below the point at which the rotor is attached to the mast.
