yinzer - 30/8/2006 7:23 PMSome areas to address, in no particular order. Is this the same launch vehicle as LV 24/25 in the ESAS report (page 420)? Is it going to need a support tower to withstand wind loads during rollout? (the Cd for a cylinder is 0.6, the Cd for a flat plate is ~1, pitch seems to be the relevant axis, and it looks like Direct will have more bending loads at it's base than STS).
Can you sketch a rough budget sand-chart and manifest through first lunar flight? It feels like this requires spending a lot of money up front for launch vehicle development and then carrying the subsequent large-ish operating costs during the EDS and LSAM development and shakeout periods when there will be comparatively low flight rates.
kraisee - 1/9/2006 1:24 AMYes, I don't believe "perfection" is achievable in the modern climate of economics and politics.But I think "effective" is possible, and I consider Ares-I and V to be "effective" in their roles."Direct" is a better solution still, and continues to fulfill all of the political objectives too IMNSHO.

Ross.At very least, *Direct* should provide a funny Orbiter addon to play with António
braddock - 1/9/2006 5:58 PMShesh, you've already modeled it?
AndyMc - 1/9/2006 8:45 PMGreat stuff António. If only the real ones came as fast! How long until you release some of these 'toys'
AndyMc - 1/9/2006 8:45 PMI've been a bit busy with a few of my own, based on NASA's DRM - http://gltrs.grc.nasa.gov/reports/2002/TM-1998-208834-REV1.pdfSome more details of the add-on: http://www.aovi93.dsl.pipex.com/my_orbiter_addons.htmAnyone working on the Ares V to launch it?
Zachstar - 2/9/2006 3:58 AMWoah SimC that is one beautiful rocket!!I hope you are backing up these like what 20 different models now? Sounds like ALIENS is on the backburner again eh? Keep up the good work!
simcosmos - 4/9/2006 1:49 PMTo end this already loooong post: thanks to Ross for the interesting emails about Direct!
