HEATING EFFECTS AND ENDURANCE PROPERTIES OF THE 3 IN. A. A. GUN M3 AS DETERMINED BY RAPID FIRE TESTS

Abstract

After 247 rounds of rapid fire, the gun and recoil mechanism was still functioning. The maximum observed temperature of the gun was 430 deg. C., which was about 110 deg. below the maximum allowable temperature. The maximum observed temperature of the recuperator oil was 95 C. Erosion was not excessive. Range dispersion did not increase appreciably during the firings. Comparison of the heating effects of pyro and NH powder were obtained, also, the effect of removing a portion of the band. Data were secured from which the heating effects, and the temperature at various rates of fire were computed.
