Soon to be completed drag reduction testing on the C-17 transport aircraft could lead to design changes that would save the Air Force as much as 7.1 million gallons of fuel and up to $48 million per year. The 418th Flight Test Squadron at Edwards AFB, Calif., is nearing the end of its year-long project to reduce drag and increase the fuel efficiency of the C-17, according to a release. The team has used 3-D printed parts and laser positioning to produce five modifications of the C-17 external configuration to best gauge how to reduce drag on the aircraft, which is “the largest consumer” of fuel in the Air Force. Recent configurations have featured the addition of microvanes and fairings to the aircraft. Each configuration is flight-tested using identical conditions so that engineers can determine which produces the greatest improvement in efficiency. The project’s final flight is scheduled to take place in December.
The last remaining T-1 Jayhawk at JBSA-Randolph, Texas, took its final flight to the "Boneyard" at Davis-Monthan Air Force Base, Ariz., on July 15. The 99th Flying Training Squadron will train pilots using T-6 and simulator until it gets T-7 Red Hawk in fiscal 2026.
