The Ram Accelerator: Review of Experimental Research
The University of Washington ram accelerator facility has a 16-m-long test section and a 38-mm-bore light gas gun for a pre-launcher (Figs. 8 and 9). The first 4 m of the test section are comprised of thick-walled tubes (203 mm O.D.) for high pressure experimentation, i.e., fill pressures up to 200 bar. The launch … See more

Ram accelerator - Wikipedia
A ram accelerator is a device for accelerating projectiles or just a single projectile to extremely high speeds using jet-engine-like propulsion cycles based on ramjet or scramjet combustion processes. It is thought to be possible to achieve non-rocket spacelaunch with this technology.
It consists of a long tube (barrel) filled with a mixture of combustible gases with a frangible diaphragm at either end to contain the gases. The projectile is fired by another means (e.g., a light-gas gunWikipedia · Text under CC-BY-SA license- Estimated Reading Time: 5 mins
