A RADIOMETRIC METHOD FOR APEX SEAL WEAR MEASUREMENTS IN ROTARY ENGINES

A radiometric method has been developed to measure apex seal wear in rotary engines. Seal wear rates are measured in ranges of micrograms/minute without engine disassembly, and at various speed and load conditions using a dynamometer. The method incorporates radioactive apex seals in the front rotor of a Mazda 10A engine. Neutron irradiation of commercial carbon-aluminum apex seals produced radioisotopes of iron and chromium. Experimental carbon-aluminum seals, containing terbium oxide as an additive to improve the nuclear properties of the seals, were also used.
