Hell, I'd say go for it and get the journals. If I could afford to do the same for IEEE and AIAA (my roommate gets AIAA, I get IEEE), I'd definitely go for it. You never know when that stuff could come in handy. I have a bunch of declassified documents from my summer spent at Wright Patterson Air Force Base if anyone is interested in copies of them.

In one of them is a paper about the ISAS VTVL demonstrator: http://rosina.catchword.com/vl=50987007/cl=13/nw=1/fm=docpdf/rpsv/catchw ord/aiaa/00224650/v38n1/s10/p36 It answered a couple questions I had about the vehicle: Q: What is the attitude control? A: Nitrogen thrusters at the top of the vehicle. Q: What is up with the bright orange exhaust plume on a hydrogen engine? A: Engine throttling is by throttling the oxygen only, so at hover or descent it is running WAY rich. Ground support is billed as extremely streamlined for lox/hydrogen, but it still seems pretty shitty from a peroxide engine standpoint, with several hours of work necessary for a 20 second maximum flight. I have a half dozen or so AIAA books, but I am moving into a new house with a real library soon, so I am sorely tempted to pull a rare extravagant-rich-guy thing and say "send me EVERYTHING!!!". :-) John Carmack _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
