The RAMAC, short for ram accelerator, is a relatively new concept of hypervelocity launcher. It was first proposed by Prof. A. Hertzberg of the University of Washington (UW) in 1980s [1]. The principle of a ram accelerator is similar to that of a ramjet/scramjet engine. The projectile, similar in shape to the center-body of a ramjet, is launched by an initial launcher such as a powder gun or gas gun, at a certain velocity and then enters a stationary tube filled with premixed gaseous propellant (typically combustible gas, oxygen and diluents).
