So then Ric, you are saying that the oxidizer is contained in and is part of the propellant ?......

...........then once combustion is initiated, it could be a good way to burn in space ?......it would override the need for hypergolics then, or is it a form of that ?......and on second though, I guess not, as the " ignite on contact" properties of hypergolics wouldn't allow any storage of the fuels until needed.........?

My appologies for straying the original thread...but I was thirsty for info......the concept of the dark continent of Africa being camouflaged as lunar proximity is a neat one....good going on the developers part !

Yes,

The propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent). The propellant is an 11-point star- shaped perforation in the forward motor segment and a double- truncated- cone perforation in each of the aft segments and aft closure. This configuration provides high thrust at ignition and then reduces the thrust by approximately a third 50 seconds after lift-off to prevent overstressing the vehicle during maximum dynamic pressure.

The SRB, once "ignited" cannont be switched off, so in that sense "hypergolics" is the right word I guess. The SRB's are stored at a remote facility....away from naked flames!

Now this is the real SST that it was based on,(well, sort of) and is built by as I believe, Rockwell. And is operated by NASA & the USAF. A very talented fellow who goes by the name of "Ace Lomcevack" designed and made the "SR75" pictured in the post above and he has a site where these and many other projects he has as well as some cool scenery is called "Aeroworks" at http://www.simviation.com/aeroworks/
I was proud to have been a contestant in that race, and to have had the oppurtunity to know Ace, and his work. Also to have known the 1500 or so pliots who competed in "Mission Moon" Cheesy

That is actually a XB-70 Valkyrie I believe...

Yep that's right Pippin, it is. And ya know what's funny is that it's not all that new a concept, heh, it's been around since the 60's I was surprised to see this image of it from the 60's......though it was probably just an idea at the time and may not have actually been built till later years.........

Yeah, silent, he does make some pretty interesting stuff.
He also has some fs video's at aeroworks, that are cool....yes he's quite a fellow 8)

HEHEHEHEH! I might want to try that, just for the challenge of it! Where can I download that kite (with shuttle attached)?

Well Ender, I still havent been able to locate any BOTA stuff on the net, however I still have all the files from the entire race on my drive, and in zipped form as well.
I'd be more than happy to send it to you via e-mail if you'd like.
The files are for fs2002, and the zip for this particular craft will contain all the files that were required for that stage of the race, so you would only want to install the aircraft only, and not the entire zip, as it contains scenery and other stuff like an .exe, a module ect. that were required to run that stage and wouldnt work unless you had BOTA software installed as well.
