The Electrostatic Sensing of Simulated MA-1A Gas Path Distresses.

Abstract

Jet engine distresses were simulated using a MA-1A start cart. Three primary methods were used to distress the gas turbine engine. Material was ingested through the compressor intake, the compressor section was rubbed with an aluminum rod, and foreign material was burned in the combustor can. The current wave forms created by these distresses were observed with four separate detectors. Since the MA-1A was on rubber tires, the current between the chassis and ground could be measured. This chassis current was equal to the rate at which charge was expelled in the exhaust. A Gaussian ring around the exhaust port provided a second way of detecting charges leaving the start cart. The third and fourth devices were an ion probe and a screen that were placed in the exhaust.
