Re: REFLECTOR: Pictures of the air intake on my bird


Here is a thought.

Think of a straw attached to the side of the plane.   Wind will go through
that with very little drag.  Put in a flap with an actuator.  I would think
that if you put in a temp probe in  the plenum at the hottest point, and
attach this to a microprocessor.  At a certain temp rang, have a servo open
up the flap a little to force more air into the cowl.  You can also have a
Pilot controlled flag also instead of the microprocessor..  This way, the
flap is open just enough to ram in the air that is needed.  The rest should
go out the back.  While on the ground and camping under the wing, you have a
place to put the newspaper without getting wet :)  Of course close the flag
to keep the bugs out.
