After having evaluated the technology demonstrations during the last years... They say it is feasible to start working on it.

"to integrate and conduct ground tests on key structural elements of a reusable, quick-turnaround space vehicle"

Re: Military Spaceplane outline - By Northrop Grumman

This http://www.fas.org/irp/mystery/nasp.htm]site gives more information about how such a thing may work in non marketing/press release talk.

I'm halfway through it and basically what I'm getting, its not possible, or rocket propelled planes are still better.

Re: Military Spaceplane outline - By Northrop Grumman

I have been looking up the problems that you encounter at hyper sonic speeds (above mach 8) a biggie is heat.

Looking at the http://www.key-to-steel.com/]key-to-steel site. Which is a paid for database containing 29.000 alloys and their properties. But there are some free articles. I found this http://www.key-to-steel.com/Articles/Art88.htm]article which states in this http://www.key-to-steel.com/Articles/im … if]graphic  (as an example) that alloys tend to be more heat resistanced but also become more breakable, brittle, fragile.

So its my gues that you use something like http://en.wikipedia.org/wiki/Aerogel]aerogel or wait for space stations that are able to make better alloys in zero gravity.

Re: Military Spaceplane outline - By Northrop Grumman

Fixed topic shifting issue but it really should be merged with the other one that has bee updated as well for space plane discussion... Space Plane - Space Plane

Of course here is another small topic Falcon - Pentagon Suborbital Spaceplane should be appended as well.
