Paul,
        Got the P Port mockup engine installed and mocked up the slide
   throttle
        and headers.  I think I can get the same length described in
   the NACA
        report for rectangular augmenter by putting it on top.  The intake
        runners will run down to the wing root area in back of the spar
   far away
        from the exhaust.  I can use a small armpit scoop or a NACA for
   engine
        charge air.  The headers are mocked up with PVC pipe 2" ID so
   they will
        be a lot smaller in dia.  I want to put a heat shield around it and
        plumb it up to the augmenter and put the opening in the bottom
   toward
        the rear to get airflow around the headers.  The last picture
   is a 3" X
        10" furnace duct that will be shorter to clear the prop circle
   and will
        flare out in the front to confor to the inner shape of the
   upper cowl.
        The whole cowl will be sealed.

   Looks pretty good to me, I think.  Please doodle into the picture (using
   MSpaint or similar) the path of cooling air through the engine
   compartment.  In the belly and out the eductor?  You might still need
   some strategically placed heat shields on the pipes - like where they
   run close to the motor mount and firewall.

   Do you read the canard aviators Yahoo group, Joe?  Al Wick recently
   mentioned running the exhaust close the prop hub will lead to hotter
   blades then if exhausted further outboard. Maybe too hot.  Mixing the
   engine exhaust air with the cooling exhaust air will help some, but it
   may be difficult to tell how much.

   There's no rule saying the system has to be perfectly symmetrical
   left-right.  The exhaust and cooling air could all exit the cowl to one
   side.  Maybe on left side of the airplane - opposite where the stacks
   come out of the engine.  That might allow an augmenter of more
   idealized
   proportions - the exhaust stack would end near the front of the
   augmenter.


   Regards,

   Matt-

   Here is some visual data on the subject Matt. This the p-port 2 rotor
   Velocity aircraft that went 205 MPH in the Dayton to OSH race. It
   has an augmenter.
   There is little or no exhaust discoloration on the prop.

   Paul Lamar ...No rotor no motor.

Cool..
