Advanced CMS
Abstract
WR-ALC uses the Capacitance Measurement System (CMS) to determine fastener hole quality on C-141 and F-15 aircraft. The size of the original CMS system (300 pounds) made it inconvenient in the work area and affected reliability, accuracy, and repeatability of the system. Vibration problems, associated with transporting the unit across the flight line, affect the system reliability. Accuracy and repeatability are affected by the need of a long reach cable for the hole probe to reach all work areas on the aircraft without constantly moving the machine from location to location. The fifty foot reach cable that is required for the CMS is shielded; however, electromagnetic interference will still occur.
