* The Quicklaunch will cost $562 million to develop over 4 phases and 8 years
* One thousand pound payloads.
* 10-28% payload fraction (full scale system will have 28% payload fraction)
* the donuts around the tube are for bouyancy and for rigidity and precision alignment
Quicklaunch designs shows that all of the high-g issues of my nuclear cannon design can be resolved. If larger projectiles have issues then can launch many smaller projectiles at the same time. The nuclear launch system can achieve the 9km/sec speed so no booster is needed. The nuclear cannon can have a deeper hole to allow reduced g-forces even when accelerating to 9 km/sec instead of 6 km/sec.
The video below shows a high g-hardened satellite that was built.
How to Shoot Stuff into Space
STEP 1: HEAT IT
The gun combusts natural gas in a heat exchanger within a chamber of hydrogen gas, heating the hydrogen to 2,600˚F and causing a 500 percent increase in pressure.
STEP 2: LET THE HYDROGEN LOOSE
Operators open the valve, and the hot, pressurized hydrogen quickly expands down the tube, pushing the payload forward.
STEP 3: TO INFINITY AND BEYOND
After speeding down the 3,300-foot-long barrel, the projectile shoots out of the gun at 13,000 mph. An iris at the end of the gun closes, capturing the hydrogen gas to use again.
