IV.I.13. ETC and EM Armaments for Direct Fire. Demonstrate the technical feasibility of Electrothermal Chemical (ETC) propulsion for the near term (20052010) and Electromagnetic (EM) launch for far term ( 20152020) integration into direct and indirect fire weapon systems. EM offers potential for hypervelocity launch at >17MJ with increased and flexible lethality against advanced threat defensive systems, increased hit probability, reduced firing signature, propellant elimination and synergism with an all-electric vehicle system. ETC offers potential of increased muzzle energy and improved accuracy at an order of magnitude less pulse power requirement than EM. ETC will provide current 140mm lethality for projectiles fired from a 120mm, XM291 cannon. EM focus through FY99 will be on maintaining a robust pulse power development effort with subscale rotor demonstration of 1.5 J/g energy density in 4thQ FY97 and next generation near full scale compulsator (compensated pulsed alternator-CPA) demonstration of 3 J/g energy density in 4thQ FY99. Also in FY99, demonstrate integrated launch packages (ILP) with <50% parasitic mass launched at 2.5 km/s with muzzle energy of 7MJ. ETC focus through FY99 will be on effective coupling of electrical energy into improved propellants and controlling propellant burn temperature with demonstration of 14 MJ muzzle energy from M256, 120mm cannon in FY98 and 17MJ muzzle energy from XM291, 120mm cannon in FY99. For both EM and ETC, systems analysis and critical tests will show benefits in terms of improved battlefield effectiveness, no accuracy barriers and no fatal flaws.
