A cumulonimbus cloud having protuberance-like pouches, or udders, hanging on their underside. Cumulonimbus mamma clouds normally indicate the presence of severe turbulence.
Industry:Aviation
A cupped, spring steel washer used to produce a large amount of compressive force, but with a limited amount of movement.
Industry:Aviation
A cup-type bearing in which a hardened steel pivot rides. Jewel bearings used in many types of indicating instruments are normally made of an extremely hard glass.
Industry:Aviation
A current-measuring analog electrical indicator whose needle deflection is not uniform over its entire scale. The amount of deflection for a given input is increased for certain ranges of indication. Expanded-scale meters are used when small changes in the upper limit of the value being measured are important.
Industry:Aviation
A curve formed by a flexible cable suspended between two points at the same level.
Industry:Aviation
A curve formed by points that are an equal distance from a straight line and from a fixed point.
Industry:Aviation
A curve formed in more than one plane. The surface of a sphere is a compound curve.
Industry:Aviation
A curve plotted to show the instrument errors at different points on the scale. The error at each point is plotted on a graph, and these points are joined by a smooth curve.
By using the calibration curve, it is possible to interpolate the error at points between those which have been plotted.
Industry:Aviation
A curve showing the relationship between the flux density (B) in a piece of magnetized material and the magnetizing force (H) needed to produce the flux density.
Each type of ferromagnetic material, material that contains iron and is magnetizable, has a different B-H curve.
Each B-H curve consists of the virgin magnetization curve, the curve of B and H, when the material is first magnetized, and the closed hysteresis loop that shows the effect of hysteresis, the magnetism that remains in the material.
Industry:Aviation
A curve showing the way flux density in a magnetic material varies with the magnetizing force applied to it. The shape of a hysteresis loop gives an indication of the magnetic characteristics of the material.
