Design, development, and field testing of a high-capacity, high- efficiency air filter for application on light aircraft engines were studied. Radioactive tracer techniques were employed and a mobile gamma radiation scintillation spectrometer circuit was utilized for rapid wear analyses in flight tests. The top piston ring of one cylinder of a H-23C helicopter engine was irradiated by neutron bombardment, and its wear measured when the engine was protected with various filters and also with no filter in the induction system. A reduction in piston ring wear by a factor of three was noted when the engine was protected with a highcapacity, high-efficiency air fiIter to one that had no filters. (auth)
