Cheers,
I replied to similar over another thread. the duct itself is a
proven design, and I copied mine from a Rutan drawing of the original. It
became a 10"x3" inlet and works even at slow speeds (automobile test). The
inlet at that size feeds a sympathetic 2" duct exactly. I made mine from a
Cedar plug which takes wax very well and will produce several copies very
easily - then make a 3"x1" recangular to 2" diameter circular cross-section
to fit the ducting. Produces a very strong current of air which can be
throttled or otherwise controlled for cockpit hot/cold.
