Impact Fuze Tester Improvement Study

Abstract

This report contains an analysis of the effect of test variables on test results including: (1) fuze weight; (2) drop height; (3) impairment of free fall conditions; (4) securing of Fuze to test fixture and (5) impact surface area. The following improvements to the Drop Test Fixture were made: (1) modification of the cabling from the Impact Fuze to the amplifier circuits; (2) improvement of finishes for the sliding surfaces of the fixture and (3) modification of calibration (dummy) fuze to simulate the production configuration to a greater degree. These improvements have reduced test time by providing a higher degree of 'g' load accuracy and repeatability making it possible to obtain the proper test 'g' loading without requiring constant re- adjusting of the test parameters. In addition, the number of tests to be performed on each fuze was reduced thereby resulting in a reduction of testing wear and tear on the fuzes, as well as improvement of fuze reliability.
