Design and Fabrication of 8-Inch Extended Range Ammunition. Sabot Technology Study
Abstract
The 8-inch subcaliber ammunition development program described in this report culminated in the successful flight tests at Yuma PG during which the greatly enhanced range capability of the prototype hardware was demonstrated. The range goal of 40 km was exceeded, thereby doubling the range capability of the 8-in. weapon firing the standard M106 round with zone eight charge. Recommendations for future work include: (1) Specific effort should be expended to develop an optimized charge for propelling the 8-in. subcaliber cargo ammunition. (2) A goal fo the current program was development of a sabot system which would permit effective and repeatable gun launch of the 8-in. subcaliber round and also cleanly discard without causing tipoff or fin interference. While this goal was achieved, the sabot system contains metal parts which brings up the question of a safety zone requirement in front of the gun. Since work has been ongoing to develop a frangible sabot system, these efforts should be applied to the 8-inch subcaliber round. Other topics needing further study are: Base ejection; Thin body shells; Shot start and fall back; Field handling; Fin manufacturing; and Aerodynamic data.
