Butterz Posted November 14, 2010 Share Posted November 14, 2010 Investing in technologies is never bad. Who knows if they are successful, then they will make more $$ in long run by selling tech to other countries. To fix something you need to fix root cause. Root cause of bad economy is this useless wars and other things. They need to stop doing that and they need to learn to stop brown nosing in other countries rules and regulation. War in Iraq: Nothing found. War in Afghanistan: Nothing found much either. It's funny to me that USA was first giving weapons and $$ privately to Afghanistan to keep silent war against Russia and then slowly Afghanistan turned back on US itself. There goes saying, "As you sow so shall you reap." Even though it is good that money is being spent on R&D, its a shame, in my opinion, that the ultimate end goal is monetary, not discovering for the benefit of people. Things like the Bugatti Veyron, and extremely cool car, amazing as it is, will probably not be made again, because it is not cost-effective.

ajnl Posted November 15, 2010 Share Posted November 15, 2010 Mach 20? May not sound like much but here is the math for you. Lets say it is a high altitude craft traveling at around the same altitude as the SR-71 at 80,000 feet (24,384 meters) and in temperatures of around -50C (-58F). This means it is traveling at roughly: 19,744 feet per second which is roughly 3.74 mi/sec. In metric measurements that is about 6,018 meters per second or 6.01 km/sec. If it operated at low altitudes at 60F (15.56C) it would be traveling at roughly: 22,368 ft/sec or 4.24mi/sec or 6,817.8m/sec or 6.82 km/sec. *Difference in air resistance at the different altitudes not included in calculations as I do not know how. I believe to figure out the air resistance, you need to take in account the compressibility effects. Since your going at high speeds :-P Quote Link to comment Share on other sites More sharing options...
AntiThought Posted November 15, 2010 Share Posted November 15, 2010 Actually I suppose I would not have to figure out air resistance as it is not needed as NASA's target speed is Mach 20 regardless of air resistance. Quote Link to comment Share on other sites More sharing options...
iSpooky Posted November 15, 2010 Share Posted November 15, 2010 im pretty sure i run faster than those things ;p Quote Link to comment Share on other sites More sharing options...

eagle7wolfensteiner77 Posted November 25, 2010 Share Posted November 25, 2010 Forget planes, I want a car that goes Mach 10 Quote Link to comment Share on other sites More sharing options...
gunsling3r Posted November 25, 2010 Share Posted November 25, 2010 A project like this is gonna need more that 15 million dollars. But it would be interesting to see how this goes. Quote Link to comment Share on other sites More sharing options...
