Abstract:

Ram acceleration is an emerging propulsion technology which appears capable of producing very high velocities with significant masses. Work at the University of Washington has demonstrated velocities in excess of 2.6 kms in 38-mm caliber, while theory predicts velocities in excess of 10 kms may be obtainable, Following a brief introduction to the theory of ram acceleration, advantages and disadvantages of the technology for large caliber hypervelocity applications are examined. An empirical performance analysis of a scaled-up ram accelerator 120-mm is presented and compared to a theoretical analysis of conventional solid propulsion. A theoretical and experimental program ongoing at the Ballistic Research Laboratory to explore scaling the technology to 120-mm is then described.
