When an aircraft flies inverted the air flows over the "lower" (relative to the aircraft) wing surface faster than over the "upper", so Bernoulli applies just the same as when it is the right way up. The interesting question is how the speed difference develops, which is not much to do with Bernoulli, but that is third year degree stuff, and too long to explain here. The aerobatic aircraft that do this sort of thing habitually usually have symmetrical wing sections (i.e. no camber). -- Ken Moore [EMAIL PROTECTED] Web site: http://www.mooremusic.org.uk/ I reject emails > 100k automatically: warn me beforehand if you want to send one _______________________________________________ Finale mailing list [email protected] http://lists.shsu.edu/mailman/listinfo/finale
