I have next to no knowledge in the field of aerodynamics- I stumble to explain the two competing theories of how a wing works, how coupled and uncoupled canard-deltas differ – even the simple equations of Energy Management have me stumped (not even sure this last one solely exists in aerodynamics). So I’m hoping that some bright aerodynamic engineer can help me with this one – ideally using simple language. Why does the F-35 produce such distinctive vortices from the wingtip/flap edge – and are they intentional, and positive in effect? Agile fighters – with strakes or canards – display visible vortices on the inner section of the wing- presumably where it’s wanted. I thought that wingtip vortices caused induced drag and were best avoided? Yet, the F-35 seems to stream them like a ’70s airliner. Educated comments in the reply section are VERY welcome.
