Air Force Working on Fuel-Saving, 3D-Printed ‘Microvanes’ for C-17 | Air & Space Forces Magazine

The Air Force is considering retrofits of small microvanes to its C-17 cargo planes in an effort to save on fuel.

C-17 Microvanes

Aerodynamic technologies for mobility aircraft promise high return on investment

As part of its effort to increase readiness and capability, the Air Force is working to introduce aerodynamic technologies on mobility aircraft to improve airflow, reduce maintenance issues, increase

After several years of research and testing, microvanes for the C-17 are in the process of airworthiness certification at the AFRL and the Air Force Life Cycle Management Center. Microvanes are small 3D-printed structures that attach to the aft-end of the fuselage. The fin-like shape helps redirect airflow in this higher drag area, streamlining the aerodynamics and reducing overall fuel demand by approximately 1%.
When installed across the C-17 fleet, including Air National Guard and Air Force Reserve aircraft, the Air Force estimates the microvanes will pay for themselves in fuel savings in seven months, and save over $10 million per year.
