REFLECTOR: Nose OIl cooler scoop flaw

[Douglas Holub]

   On August 3, 2002, Tim Crawford suffered a stroke while flying his LongEZ 
aircraft south of Martha's Vineyard during the CBLAST experiment.
     Tim was the Director of NOAA's Air Resources Laboratory's Field 
Research Division in Idaho Falls.  He joined NOAA/ARL as a physical 
scientist in 1986; prior to that he was a research analyst and an 
environmental engineer for the TVA. Tim received a Ph.D. in Mechanical 
Engineering from the University of Waterloo (1977), a M.S. in Civil 
Engineering from the University of Illinois (1972); and a B.S. in ME from 
the University of Illinois (1971).
     Tim loved to fly.  He constructed five experimental aircraft and held 
FAA aircraft builder and commercial instrument pilot licenses.  He was an 
innovative engineer and received the Department of Commerce Bronze Medal and 
NOAA Administrator's Award, both for design and application of airborne 
instrument systems.  Finally, Tim was an extremely versatile scientist.  As 
he once said to Jerry Crescenti of NOAA/ARL: "It's not about the flying. 
It's about the science."

>>I was the one who added VG's in front of the scoop and I also have a 
>>smooth
>>transition at the front.  I don't know if eliminating the lip at the front
>>helps air flow as I did it before flight but  it looks nicer.  The VG's
>>aren't pretty but they are effective.  Mine are made of 3/4" aluminum
