Approaches to Reducing the Temperature Sensitivity of Propulsion Systems for Artillery Ammunition.

Abstract

A number of approaches to reduce the temperature sensitivity of ADF gun ammunition across the operational range (-6 deg C to +63 deg C) have been reviewed and analysed. Increases in range of about 5% for Hamel are possible, and a solution would maintain compatibility with the existing gun system. While successful in rocket propellants, no chemical additives have been identified which give similar control of temperature sensitivity in gun propellants. LOVA ammunition appears to offer the best potential and has the added advantage of enhanced munition and platform survivability. Two changes involving gun design are at early stages of R&D in the US; control tube primers and variable volume gun tube. Both should be monitored for future applicability, including fail-safe aspects.
