EVALUATION OF 70/30 CYCLOTOL AND 75/25 CYCLOTOL FOR USE IN HE AND HEAT PROJECTILES
Abstract
An evaluation was made of 70/30 Cyclotol and 75/25 Cyclotol for use in HE and HEAT projectiles. The 3.5-in. HEAT rocket heads containing 75/25 cyclotol bursting charges penetrated on the average 14.7 to 14.9 in. of mild steel, and similar heads containing 70/30 Cyclotol bursting charges penetrated 14.3 and 14.4 in. of mild steel in parallel tests. The 3.5-in. rocket heads containing Composition B penetrated 14.2, 14.4, and 14.6 in. of mild steel under the same or similar conditions. Similar differences in steel-penetrating ability were found in static tests of 105-mm M324 HEAT shell containing bursting charges of 75/25 Cyclotol 70/30 Cyclotol, and Composition B respectively. In a large impact drop test, cast 75/25 Cyclotol was slightly more sensitive to impact than cast Composition B, which in turn was slightly more sensitive than cast 70/30 Cyclotol. All 3 explosives had essentially the same sensitivity to rifle bullet impact. Results indicated that the ability of nonrotated HEAT ammunition to penetrate steel can be slightly increased by loading the metal parts assemblies with 75/25 Cyclotol instead of Composition B. There was no apparent advantage in replacing Composition B with 70/30 Cyclotol made from 75/25 Cyclotol as the explosive filler for HEAT rounds. The effectiveness of ammunition designed for fragmentation effect can be increased by loading the metal parts assemblies with 75/25 or 75/30 Cyclotol instead of Composition B.
