Green Aviation Project Tests Shape Changing Wing Flaps

A NASA F-15D flies chase for the G-III Adaptive Compliant Trailing Edge (ACTE) project. The ACTE experimental flight research project is a joint effort between NASA and the U.S. Air Force Research Laboratory to determine if advanced flexible trailing-edge wing flaps can both improve aircraft aerodynamic efficiency and reduce airport-area noise. via NASA http://ift.tt/1AZlddP
