New ingredients in nitrocellulose based propellants

Scientific paper for 4th International Disposal Conference, Katrinaholm, Sweden, 2006. – 2 p.In Sweden there is an ongoing effort to develop a new gun propellant for the Uniflex 2, 155 mm modular charge system aimed for a new Swedish field howitzer Archer. The Archer Artillery System is a 155 mm L/52 howitzer mounted on a modified articulated hauler. The system-solution features several advantages among which increased fire-power and mobility are a two. The propellant charge first suggested for the Archer system was a bimodular charge system with two different propellants. This is a common solution that has several disadvantages in relation to a unimodular charge where all the modules are equal. To design a fully functioning unimodular system is however rather difficult, and numerous efforts has been made (by several manufacturers) to design such a system.
