NASA tests flexible flap design
NASA has started flight testing a new flap design that has the potential to make flying quieter and more fuel-efficient. The Adaptive Compliant Trailing Edge project is a collaborative effort between NASA as part of its green aviation project and the U.S. Air Force Research Laboratory to determine whether flexible trailing edge flap surfaces can improve aerodynamic efficiency and lower noise levels produced by jet airplanes during takeoffs and landings. The flap design is a variable geometry airfoil system called FlexFoil, which was designed and built by Ann Arbor, Michigan-based FlexSys Inc.
