A fiber of magnesium silicate that is highly resistant to fire and has good insulating qualities.
Industry:Aviation
A field effect transistor having a source, drain, and channel of P-material formed on a substrate of N-material.
Industry:Aviation
A field pole in a compound-wound generator used to minimize armature reaction. Armature reaction is the distortion of the magnetic field produced by the field coils caused by the magnetic field produced by current flowing in the armature. The amount of armature reaction varies with the armature current. Armature reaction causes a voltage across the commutator segments shorted by the brushes, and this produces sparks.
Interpoles are located between each of the regular field poles, and the interpole coils are in series with the armature so all the armature current flows through them. The magnetic fields produced by the interpole coils cancel the distortion caused by the armature field, and the brushes short across segments of the commutator where there is no potential difference and therefore no sparking.
Industry:Aviation
A field pole of an electrical generator or motor that has its own pole shoe protruding radially inward from the field frame. A field coil is wound around this pole shoe. Salient poles are often used instead of distributed poles which do not have separate pole shoes.
Industry:Aviation
A field-effect transistor in which the resistive area between the source and drain is made of N-type semiconductor material.
Industry:Aviation
A field-effect transistor whose gate is insulated from the channel by a layer of silicon oxide.
Industry:Aviation
A figure formed when a plane cuts across the axis of a cylinder at an angle other than a right angle.
Industry:Aviation
A filament, or thread, of glass, usually less than one-thousandth of an inch (25 micrometers) in diameter. Glass fibers, woven into cloth or packed together into a mat, are used for thermal and acoustical insulation and for reinforcing plastic resins to make various types of molded products.
Industry:Aviation
A file that has a single row of teeth extending across its face at an angle of between 65° and 85° to the length of the file.
Industry:Aviation
A file with two series of parallel cutting teeth. These teeth cross each other at an angle.
