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 program.

 

"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."
