    They are indeed vortex generators.  You'll see them on the tailcone of
B-1s and wings of B-52s as well.  Their purpose, if memory serves me right,
is to induce a vortex into the flow to prevent it from seperating from the
surface.  In some places where the flow is likely to seperate because of
extreme surface contours, the vortex generators would help keep it attached.
I could be wrong on this one, but I think that's what they're for.  Any
input from others?
