Re: Adjustable mill heads

Anyone notice how the rear jet-pipe is manouvered on the prototype of
the fighter designed to replace the Harrier?(Forgot it's name)
2 or is it 3 truncated cones(?) rotate in unison to give a movement
of over 90 degrees. Could this concept be used in adjustable mill
heads.
