Te <<DSCF0460.JPG>> sting at NAWTF (North Austin Wind Tunnel Facility):)
last year determined the radiator angle made almost no difference with
this duct. Dennis H. and I measured the airspeed on the backside of the
core at several angles. Do not have the data handy but we observer about
a 1 mph difference across all the angles we tested. What was
interesting was the airspeed deceleration in this crude NACA duct. From
entrance to the non-existent lip the airspeed dropped by 1/3.
