A Minimum Weight Cartridge Case Design for 30 mm Separate Loaded Ammunition (SLAMMO)

Abstract

A goal for weapon system designers is to minimize the total weapon system weight. This is particularly relevant for those weapon systems that are destined for installation in rotary-winged aircraft. One of the principal parameters by which the weapon system weight is controlled is configuration and weight of the individual cartridge. In this report, the generalized analysis to determine the minimum weight cartridge case (and hence cartridge), given certain constraints such as wall and head thicknesses, and the propellant volume to be packaged is discussed. The analysis is initiated by the defining of the consolidated propellant charge required to produce a predetermined level of muzzle energy for the 30 mm Separate Loaded Ammunition (SLAMMO). The minimum cartridge case weight is then calculated by the evaluation of a generalized expression for the geometry of the case. This analysis is then applied to the cylindrically configured 30 mm SLAMMO cartridge case. Finally, additional factors are discussed that should be considered in the optimized design of cartridge cases.
