Predicted Effects of Transient Burning on Gun Flamespreading

Abstract

NOVA code calculations were performed to predict flamespreading and pressure waves in an Army 155mm howitzer full bore charge (155) and the Navy 5 inch, 54 caliber gun (5/54) with a special service charge. A Zeldovich form of a transient burning model replaced the usual quasi-steady pressure dependence of regression rate. Some differences were noted for the Army application; Navy calculations showed a wide difference. Both calculations showed that transient burning can affect an interior ballistics calculation although several refinements are needed before full gun calculations can be performed.
