Senior Airman Terrence Williamson, 736th Aircraft Maintenance Squadron aerospace maintenance journeyman, explains to Roberto Guerrero, Deputy Assistant Secretary of the Air Force for Operational Energy, Headquarters U.S. Air Force, Washington, D.C., how Microvanes positioned on each side at the rear of a C-17 Globemaster III fuselage using a Mylar template, Sept. 6, 2017, at Dover Air Force Base, Del. Microvanes essentially clean up the airflow in the region of the cargo door by re-energizing the air with small vortices that delay separation, smooth the flow, and reduce drag. “The programs APTO is working on are great examples of how we can increase our combat capability through the smart use of operational energy,” said Guerrero.
