2. Electrothermal-Chemical Propulsion Technology (United Kingdom, Israel)
Description: Electrothermal-Chemical Propulsion (ETC) is a collection of propulsion concepts which offer the potential for near-term substantial increases in projectile kinetic energy (up to 25 percent) while utilizing conventional solid propellant gun tube and projectile technology.
Justification: If successful, this program will provide the U.S. Army with propulsion technology which will increase projectile kinetic energy (up to 25 percent) and overall gun performance by up to 50 percent with corresponding increases in lethality and range. At the present time, the United States has the lead in this technology, but, over the next several years, the United Kingdom is devoting substantially more resources than the United States in the exploration of several novel ETC approaches which could benefit U.S. programs. Israeli research has already demonstrated an 18 percent increase in velocity, using electrical energy to augment and control the conventional propellant's burn.
Implementation: The effort with the United Kingdom falls under TTCP and will address advanced propellant development, modeling and simulation, and plasma/propellant interaction required to obtain weapons-level performance enhancement and repeatability. Another source for potential contributions is a classified MOU with Israel.
