accelerator (plastic resin component). A substance added to a catalyzed resin to shorten the time needed for the resin to cure. accelerator system (carburetor system). A system in an aircraft carburetor used to supply additional fuel to the engine when the throttle is suddenly opened. If an acceleration system were not used, the engine would get a momentarily lean mixture until enough air is pulled through the carburetor to meter the correct amount of fuel into the cylinders. accelerator winding (voltage regulator component). A series winding on the voltage regulator coil in a vibrator-type generator control unit. Current flowing through the accelerator winding produces a magnetic field which helps hold the points tightly closed against the force of a spring. As soon as the points begin to open, this field collapses, and the spring snaps the points open quickly. accelerometer. A sensitive instrument that measures the amount of force exerted on an object because of its acceleration. Accelerometers are calibrated in G-units (Gravity units). One G-unit is a force equal to the weight of the object. acceptable data. Data found in such aviation maintenance documents as manufacturer’s maintenance manuals, service bulletins and letters, and AC 43.13-1 and 43.13-2. Acceptable data may be submitted to the FAA for a particular repair or alteration, and it may or may not be approved, depending upon its applicability to the specific job. acceptance test. A test made by a person who buys equipment to be sure the equipment is exactly as specified in the purchase contract. All large and expensive aircraft are given extensive acceptance tests before the customer accepts them. acceptor atom (solid state electronics). An atom of a chemical element alloyed with silicon or germanium to give the material a deficiency of electrons, making the material into a P-type material. See acceptor impurity. acceptor impurity (solid state electronics). A trivalent chemical element alloyed with a semiconductor material to produce atoms that accept free electrons to complete their covalent bond. |
