Here, supposedly, is a sneek peak at the upcoming... not yet released... report on the CEV/ Return to the Moon architecture:
http://www.orlandosentinel.com/media/graph...07/18731963.jpg Here's the full article: http://www.orlandosentinel.com/news/custom...=orl-home-promo Look familiar? Basically an Apollo CSM (=CEV), a beefed up LM (4-man... but I'm sure due to budget and weight... will be cut back to 3 or 2 person). Instead of one launch on a Saturn V equivalent, there is a crew launch CEV on a single SRB "stick" configuration, and the S4B-LM piece on the shuttle-derived vertical in-line cargo launcher... Seen here, for those who haven't run across this site yet: http://www.safesimplesoon.com/media-images.htm |

No - you do - the design for the CEV launcher is basically a shuttle SRB with a liquid upperstage. Arguably the most silly idea for some time - the thrust and thus acceleration profile will be astonishing.

You can vary the nozzle and the burn cavity in a solid to change the thrust and the burn duration -- so, in theory, you *could* design the SRB to have a lower initial thrust-to-weight ratio. Of course, you'd be reducing the motor's ISP, too.
What the heck is wrong with using a Delta IV or an Atlas V for the CEV, anyway??? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
