The Air Force Research Laboratory, FlexSys and NASA completed flight tests of the Active Compliant Trailing Edge on a modified NASA Gulfstream 3 business jet to prove the airworthiness of FlexFoils for optimizing fuel efficiency and reducing air loads and airframe noise. FlexFoils are compliant airfoil structures that replace conventional surfaces for seamless, variable camber capability. On the G-3, the FlexFoil sections span 5.5 meters, plus 60 centimeters of compliant fairings on both sides to reduce noise. Here, Centolanza details shape-shifting materials which enable aircraft to adapt to changing environmental conditions during flight.
