Gentlefolk, Robert H. Goddard has a 1930's patent for what we would call a turbo-fan driven by rocket exhaust to "dilute" ISP for lift-off. It's on display (as of three or four years ago) in a cabinet by the entrance to the Goddard Museum at Roswell NM (essentially, the workshop where he built his later rockets). --Best, Gerald _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
