Vortex bursting
Cosmo
That was a great link of yours re slender deltas over on Concorde Accident Part 2
Any chance of emailing me the origins of that stuff?
As to vortex bursting, certainly the Aero Flight boffins saw this as the limit for slowing down in the 115. We used smoke generators to visualise the vortex so that a formating Auster could call stop just before the burst got to the trailing edge. By then speeds were less than 50 kts (with alphas in the 40s). The boffins were more concerned about the dramatic changes in the control forces should the burst touch the large unpowered elevons than in lift reduction issues. They suggested it could whip the stick out of your hand.
Another issue that relates to the usability of very high Cl values is what happens when one wing does eventually give up (in whatever manner). The H126 in which we reached a Clmax of 7, at the same time in history, tipped on its back too fast to see when it eventually stalled on one side.
