Can someone please explain to me the purpose of the 'dog-tooth' seen in the leading edge of later versions of the Hunter, Kestrel/Harrier etc...
I can well imagine it working to prevent span-wise flow, in much the same way as a wing fence, but imagine it moved the centre of pressure ?
I know both aircraft were said to suffer from 'pitch up' into hard turns, and the dog-tooth was a partial cure.
More confusingly, the dog-tooth was partially blended out on the Sea Harrier FRS2 - later FA2; or at least on the development aircraft I saw.
