Eidetics Awarded NASA Dryden SBIR Phase II Contract for Reduction
of Aircraft Cruise Drag by Using Boundary Layer Heating to Minimize Fuselage
Skin Friction Drag Program
March 18, 1996 -
Eidetics Corporation was awarded a contract for the follow-on Phase II Small
Business Innovation Research program for the Reduction of Aircraft Cruise
Drag by Using Boundary Layer Heating to Minimize Fuselage Skin Friction Drag.
Brian Kramer, Principle Research Engineer is the Principle Investigator for his
"The benefits of
reducing the drag of either a new or existing aircraft configuration include
increasing the aircraft's endurance (range) which is directly proportional to
its lift to drag ratio, faster top speed, quicker acceleration, shorter take-off
distances and lower direct operating costs in the form of fuel savings. For
cruise, the drag of the aircraft primarily comes from profile drag (skin
friction), induced drag (drag due to lift), compressibility drag, separation
drag and interference drag. Of these, skin friction (from the "wetted'
elements of the aircraft) typically accounts for more than 50% of the total. The
proposed innovation uses active surface heating in the turbulent regions of the
aircraft's fuselage boundary layer to reduce skin friction."
