X@ Tail Surfaces
FH1100,
Your quote: "You'd think this was rocket science or something!", struck a respondent chord.
I'd bet that the advanced design groups at Eurocopter, Bell, Boeing and Sikorsky, and MIL and everyone else for that matter, might argue that arrangement of all the pieces and parts of a new helo design so that the CG comes out in at least a controllable position and so designing the tail surfaces so that they provide the required static and dynamic stability, while not creating some of the known tail surface forced probem areas, is in fact a lot tougher than "rocket science"!
Thanks ,
John Dixson
