Flying home from Seattle to Anchorage today I noticed that the 737 had
an arc of vortex generators which began just outboard of the engine pod
and  perhaps at 25% of the chord then arched rearward as you went a bit
farther outboard and then returned to roughly 25% just before the
aileron. From the beginning of the aileron to the wingtip, there was
another series of generators much further back, perhaps 40%, that ran to
the  tip.

I presume that these most outboard series are designed to delay the
stall in the vicinity of the aileron. Can anyone provide a better
