Hmm. So, could one then just make a flat-bottomed panel, carefully aligned with the incoming airflow, with a top geometry that doesn't transmit shock waves very well, and carry that underneath the wing? (Or maybe have a flat-bottomed wing, likewise aligned, with the engines in or above the wing so as not to disrupt the bottom.) Alternately, couldn't one have both the top and bottom of the wing be aligned-parallel as above, with the leading edge between them shaped to funnel incoming air towards engines fully enclosed by the wings? Granted, those would be pretty thick wings, even if this funnelling were enough to remove any need for compressors within the engines, and that might be what kills this idea. _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
