Document acquired - in-depth SDLV and CEV plans and images

[propforce]

How do you decide what is news-worthy? (to quote an unknow journalist)<br /><br />There are literally hundreds of papers presented in the JPC, which one specifically are you interested in? There were several interesting papers on CEV as well, then there's someone's wet dream about how to produce propellant on the surface of Mars.... as a journalist, which one do/would you choose to publicize?<br /><br />The information is out there for those who knows how to look. No one tries to hide them. A list of papers and sessions on AIAA JPC, or any other AIAA meetings, is published on the Aerospace America magazine 3 months before the conference (which put them in about April, 2005), and the magazine is free to active members of AIAA. If you had known this, would you travel to Tucson, AZ and attend the conference?<br /><br />As to how many members here know about how to search info on AIAA, how many SDC members here are space professionals? AIAA publishes many conference papers as well as journal papers, and it is just one of many publications that's available. As a journalist, why don't you subscribe them all and read thru all of them, then tell us which one you choose to publish?<br /><br />Shuttle_Guy and I work in this industry and we come across many concepts, including several 'exploration architectures', we may even participate in some of these studies. But it's not something we can always talk about. <div class="Discussion_UserSignature"> </div>

"</font><br /><br />SG -- I'd just like to note for the record that I really don't have any particular desire to be informed about any sneezes, sniffles, or persistant coughs that you might experience. I can't speak for the other members of the board. <img src="/images/icons/smile.gif" />

So much for my "USA Sneeze and Sniffle update thread" <img src="/images/icons/tongue.gif" />

Part of the Space Island Group proposals are to put a Delta Clipper type vehicle on top of the stack - has NASA looked at doing this itself??<br /><br />http://www.spaceislandgroup.com/dual-launch.html<br /><br />http://www.spaceislandgroup.com/nasacost.html

 

[shuttle_rtf]

Now I've never seen that site before, but I'm glad I have now. A very interesting site..I'll have a proper look through that later.

I've started a thread in the 'Space Business and Technology' section asking how seriously their ideas are being taken.<br /><br />According to the SIG homepage they are also looking at weather control with backing from the insurance industry...

The idea of DC-X and DC-Y is awesome but we have a problem here on earth if we use it here and thats our thick atmosphere allowing all that drag and that 1g gravity thingy. On Mars and moon it would do just great since the moon has no real atmosphere with that 1/6th gravity and Mars isnt as thick as ours with 1/3rd the gravity as well<br /><br />But the fundamentals behind the DC-X was definately the storyboard for Sci-Fi... Thing is though it has to get a weight to thrust configuration where the flight body could carry real cargo and personel as a space vehicle. The concept is sound for off earth use but here on earth we need to come up with very exotic materials to build on. Maybe nano tech will help here...<br /><br />I believe the term "Drop Ship" comes to mind with the DC-X/DC-Y<br /><br />Makes you wonder what DC-Z would be like....

shuttle_guy:<br /><br />Gotta question about the SDHLV. Read an article today on Spacedaily about the Sound Suppression Water System. It noted in the article that: <br /><br /><i>"Specifically, the red water bags are used to dampen the wave of sound energy that is reflected back up toward the Space Shuttle when the Solid Rocket Boosters ignite during launch. If this powerful pulse of pressure were not suppressed, it would create a dangerous stress on the wings of the orbiter."</i><br /><br />I didn't know this was specifically for the orbiter wings. So does this mean that the Shuttle-C, being wingless -- or indeed any of the SDHLV options would not require the sound suppression? If so -- any numbers on what this system costs (i.e. theoretically would save) per launch?

 

[mrmorris]

<font color="yellow">"I can not give a fiure on the savings but it is VERY SMALL. "</font><br /><br />Yep -- figured as a percentage of shuttle launch costs -- pretty much anything is smallish. Water is cheap, but it sounded like a reasonably manpower-intensive operation which may or may not be cheap -- especially if there's a Water Suppression System department staffed with people dedicated to that task. <img src="/images/icons/smile.gif" />

You will still use the water sound suppression system for the SDLV. It will reduce the acoustic environment one has to design to for the 2nd stage and the CEV. This could mean less metals and less cost on components and its qualifications. <div class="Discussion_UserSignature"> </div>

Sounds good.
