Final phase of C-17 drag reduction testing underway
Three fairings are placed near the leading edge of the wing at the engine pylons of a C-17 for phase four of C-17 Drag Reduction testing. The fairings are placed in areas where indications of airflow disturbance were identified during computer simulations. Phase four tested the fairings along with six microvanes on each side of the aft fuselage of the aircraft. (U.S. Air Force photo/Kenji Thuloweit)
