Re: Control surface configurations (was: Typhoon)

Fast moving military subs don't need to bank into turns, either. They just
do. In a turn, the sail acts as a hydrofoil inclined into the flow. Since
the sail is above the hull, it produces a rolling moment, and the boat
(ship?) heels inboard. The control surfaces don't induce the bank, but are
actually used to counteract it. One of the flyboys is going to have to
remind us why airplanes bank. As I recall, it has something to do with not
dropping like a rock. :-o Joe
