Magnetic Propulsion for a Hypervelocity Launcher
MetadataShow full item record
The concept of using electromagnetic forces to launch projectiles to high-velocity has been pursued since the laws of electro-motion were first derived by Oersted and Ampere in the early 1800's. During the l 960's, there were a number of attempts to develop practical hypervelocity accelerators using electro-magnetic forces. These investigations did not meet with notable success [1,2]. There has been greatly increased interest in electromagnetic propulsion in recent years for a variety of applications including hypervelocity weapons, meteoroid simulation at impact velocities above 10 km/s, high pressure shock physics, and space propulsion. This paper describes an electromagnetic launcher which was developed at the Australian National University (ANU) in the early 1970's,  and was successfully used to accelerate projectiles to hypervelocities .
