XM746 Practice Fuze.

Abstract

This program is for the design and development of the XM746 Practice Fuze Spotting Charge. The primary objective of the testing was to determine which of the three spotting charge candidates, MOD 'E', ORI or MBA would reliably produce the best visible smoke cloud in a muddy target area. All spotting charges were loaded into XM747E2 fuzes and assembled to the four port 155mm, XM804 projectile. The SW522 (MOD 'E') and ORI composition was contained within the fuze. The MBA configuration was assembled. MOD E is a standard M739 Fuze with cap, cross bar holder assembly, M1 Delay Plunger, safe/army assembly and explosive booster removed, loaded with 47 grams ARRADCOM pyro mix SW522. ORI is the same fuze as MOD E except SW-522 smoke composition replaced with a red phosphorous composition. MBA is similar to MOD E except smoke charge consists of titanium tetrachloride (TiCl4) a cold smoke composition which is expelled from the fuze body by an ARRADCOM MOD E smoke ejection charge.
