A THERMOCOUPLE TO RECORD TRANSIENT TEMPERATURES AT THE BORE SURFACE OF GUNS

Abstract

The design and construction are described of a thermocouple and associated circuits capable of recording accurately the bore surface temperatures of large-caliber guns. The thermocouple consists of a strip of nickel foil between 2 steel slugs. The nickel foil is insulated from the steel slugs by a sheet of mica 3 to 10 u thick. Five rounds were fired on the 3-in./70-cal type E Mod 0 gun using the thermocouple. The face of the thermocouple was recessed from the bore surface from 0.035 to 0.050 in. in all 5 rounds. Temperature- and pressure-time curves are included. The thermocouple showed excellent durability in the firings.
