- Company Profile:
The length of time a part is left in the penetrant when preparing it for inspection by the fluorescent or dye penetrant method. The hotter the part and the longer the penetrant dwell time, the smaller the fault that will be detected.
Industry:Aviation
The load on a bearing parallel to the shaft on which the bearing is mounted. Thrust produces an axial load on a bearing.
Industry:Aviation
The load on a bearing perpendicular to the shaft on which the bearing is mounted. Centrifugal loads are radial loads.
Industry:Aviation
The loading of a propeller disk that causes one side to produce more thrust than the other side.
Industry:Aviation
The loss of thrust produced by a turbojet or turbofan engine caused by the increase of velocity of air entering the engine. Ram drag is the difference between gross thrust and net thrust.
Industry:Aviation
The magnetism that remains in the field frame of a generator when no current is flowing in the field coils.
Industry:Aviation
The major component in a gage-pressure measuring instrument. It is a thin-wall metal tube that has an elliptical cross section and is formed into a curve. One end of the tube is sealed and connected to an arm that moves the pointer across the instrument dial, and the open end is anchored to the instrument case. The pressure to be measured is directed into the open end, which causes the elliptical cross section to become more circular. As the cross section changes, the curve straightens and moves the pointer over the dial by an amount proportional to the amount of pressure.
Industry:Aviation
The material that bonds the fibers together in an advanced composite structure. The matrix carries the stresses into the fibers.
Industry:Aviation
The maximum amount of tensile load, in pounds per square inch, that a material is able to withstand without permanent deformation.
Industry:Aviation
The measurement of time used by the FAA for inspection and certification purposes. One calendar month from a given date extends from that date until midnight of the last day of that month.
