If the louver positioning mechanism should fail for any reason, the
louvers might blow shut.  This would be an in flight disaster.   As a
fail safe, perhaps the louvers could be made somewhat narrower than
the openings.  e.g.   three inch wide louvers placed four inches
apart.    Even when  fully closed some air would pass through the
radiator.

  We have the plenum, radiator and louver panel  which I think will
have to treated as one unit. The rad will be  firmly attached to the
airframe (not the engine) with the plenum attached to one side and
the louver panel attached to the other.  The cowl, which will have an
enormous hole cut out of the bottom will also have to be attached to
the rad to stabilize it and to keep the transition from the cowl to
the louver panel air tight.  A  360 flange  that the louver panel and
the cowl  attached to could be bonded to the sides of the radiator.
Lots of details to work out.  Maybe (probably)there is an easier way,
but this is the best I can come up with thus far.    Jerry
