Vortex Lift

Clive,

Thanks for the diagrams about vortex lift.

I seem to remember, as a flight test engineer having the good fortune to sit in on a fair number of landings during Concorde 'DG development and certification flying, that you could feel the onset of vortex lift from a very light vibration through the airframe, during the slowing down to approach speeds. I think it was more noticeable sitting back at the FTE seats at the instrumentation area in the cabin rather than on the 4th seat on the flight deck. I cannot remember if that was close to the 7 degree onset alpha or something closer to the approach alpha. Has anyone else commented on this?

Andrew
