claim: William Cohen is from Oregon.
evidence: 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 .. projectile. projectile. jet-engine. jet-engine. ramjet. ramjet. scramjet. scramjet. It is thought to be possible to achieve non-rocket spacelaunch with this technology .. non-rocket spacelaunch. non-rocket spacelaunch. It consists of a long tube -LRB- barrel -RRB- filled with a mixture of combustible gases with a frangible diaphragm at either end to contain the gases .. frangible. frangible. The projectile is fired by another means -LRB- e.g. , a light-gas gun or railgun -RRB- supersonically through the first diaphragm into the tube .. projectile. projectile. light-gas gun. light-gas gun. railgun. railgun. Then the projectile burns the gases as fuel , because it is shaped like a ramjet or scramjet core , and accelerates under jet propulsion .. projectile. projectile. ramjet. ramjet. scramjet. scramjet. Other physics come into play at higher velocities .
