I recall a group at UCLA that was working with these. They ran into a number of problems which would make PDEs less than optimal for ERPS, including difficulty of control of a non-continual stream of thrust (though the group at the link you gave seems to have overcome this), and a lower ISP than liquid fuels (which I saw no mention of at that link). In general, lower ISP means a less desirable rocket fuel, so if PDEs in general (rather than just the ones that group explored) turn out to have a lower ISP, that would explain why you see so few people working on this. (I.e., explosion power would be more like the previous level than the next - again, as measured by the ISP.) _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
