The pulser (pulsed liquid sodium electromagnetic generator) is a device for directly powering railgun kew weapon launchers. it replaces customary pulse-forming elements for railgun pulse-electrical power. pulser potentially saves system weight and complexity and also can improve efficiency by… More

Xerad proposes to investigate the utilization of the advanced nuclear reactor technology concept known as the particle bed reactor (pbr) which was baselined for an air force astronautics laboratory (usafal) study for an orbit transfer vehicle (otv). the study focused on hydrogen as the working… More

The proposed concept is the application of hot hydrogen from a compact, high-power (classiied) source to mix with, and heat ambient supersonic air in a scramjet duct to high temperatures. the study program will characterize such a system, investigating flow aerothermodynamics, induction of hot gas… More

In 1971 australiams barber and marshall railgun-accelerated a small projectile to 7 km/s; spawning a new era of electric hypervelocity launchers for weapons, space launch, and impact fusion. among electromagnetic candidates only the railgun achieves multi-kilogee accelerations needed for… More
