Abstract : Proposals were made by TEDECO, the chip detector contractor, to increase th e power of the chip detector system installed in UH-60A aircraft by approximately six fold. The work described is an effort to determine what, if any, effects this might have on the lubricant. A test lubricant system was constructed consisting of an oil sump, test lubricant pump and wear metal generator, and a TEDECO Model E1103H Zapper console and A615 full flow debris monitor. Several MIL-spec oils were received for test. Following the determination of baseline physical and chemical properties, including an in-house developed technique for determining the chemical composition, test runs were made simulating actual operating condition. In addition, a small sample of the test oil was subjected to 1000 zaps, at operating temperature, by the manual addition of metal particles, to concentrate the zapper effect. Following the tests, the used oils were analyzed and compared to the pre-test results. None of the tests could detect any significant changes in the oils due to the operation of the chip detector. However, in several cases, with the wear metal generator operating, a black, sludgelike material formed in the gap around the detector rendering its 'zapping' function inoperative.
