Experimental Testing of a Combustible Case for the 155mm Howitzer

Abstract

A limited experimental program was conducted to investigate potential ballistic advantages associated with the use of rigid, combustible cases for high-performance artillery charges. Five candidate ignition systems were evaluated for use with the combustible case. An igniter consisting of a Class 5 black powder snake without a basepad was selected, and thirty-nine test charges were assembled and fired with this ignition system. Cold- and ambient-conditioned test charges exhibited lower ignition delays and pressure-wave levels than did the standard zone 8 control rounds. Somewhat higher pressure-wave levels and maximum chamber pressures, however, were experienced with hot-conditioned test rounds when compared to data obtained firing bagged charges employing the same propellant lot. Case residue was minimal under all conditions.
