So Busted November 12, 2004 Posted by Murdoc Busting the Sound Barrier (Click image for a better look) Strategy Page has an awesome gallery of planes breaking the unbreakable barrier. Follow the link above this pic. Definitely worth a look.

Did you see that a scramjet dropped from under a B-52 (as I recall) will try to break MACH 10 (for about 10 seconds) sometime next week? Then, that project is over. No more funding. Seems a shame. I am eagerly awaiting the flight. I didn’t know the project was complete after this flight, though. Bummer. Technical question murdoc: What’s the difference between a scramjet engine and a ramjet engine? I think the only real difference is that scramjets don’t slow the airflow down and the combustion takes place at supersonic speeds within the chamber. Less loss and higher speeds are capable with scramjets. I googled and this was number 1: http://www.aviation-history.com/engines/ramjet.htm BTW, the Army is looking at scramjet-powered tank rounds. Anyone have any info on this? http://www.murdoconline.net/archives/000397.html See the latest post at ACE, the superior A-Team web site, for a clear explanation of the difference between ramjet and scramjet.
