A Miniaturized Gap Test

PDF Version Also Available for Download.

Description

A test arrangement and procedure has been devised for a miniaturized gap test in which the donor is essentially a length of hypodermic needle tubing loaded with an exploslve. The particular size used in the work reported hereln had an explosive column charge diameter of 33 mils. The procedure was used to determine gap sensitivities of several explosives including tetryl, RDX, PETN, HMX, and PBXN-5. Several of the explosives were tested of more than one particle size and loaded at more than one density. Within the group of explosives tested, both particle size and loading density had more affect upon ... continued below

Description

A test arrangement and procedure has been devised for a miniaturized gap test in which the donor is essentially a length of hypodermic needle tubing loaded with an exploslve. The particular size used in the work reported hereln had an explosive column charge diameter of 33 mils. The procedure was used to determine gap sensitivities of several explosives including tetryl, RDX, PETN, HMX, and PBXN-5. Several of the explosives were tested of more than one particle size and loaded at more than one density. Within the group of explosives tested, both particle size and loading density had more affect upon sensitivity, as measured in these tests, than did composition. The coarser materials were found to be both less sensitive and more variable than the fine explosives. The fine explosives were found to become less sensitive as the loading density increased. This trend was apparently reversed for the one coarse explosive (RDX, Class a) for which data was obtained. The test arrangement and procedure is a promising tool for the acquisition of data for the design of fuzes of minimum dimensions.
