National Aeronautics and Space Administration Volume 56 Number 7 November 2014 ACTE takes flight New flap may validate new technologies By Peter Merlin NASA Armstrong Public Affairs NASA’s green aviation project is one step closer to developing technology that could make future airliners quieter and more fuel- efficient with the successful flight test of a wing surface that can change shape in flight. This past summer researchers replaced an airplane’s conventional aluminum flaps with advanced, shape-changing assemblies that form seamless bendable and twistable surfaces. Flight testing will determine whether flexible trailing- ED14-0338-081 NASA/Ken Ulbrich edge wing flaps are a viable approach Above, for the initial ACTE flight, to improve aerodynamic efficiency the experimental control surfaces were and reduce noise generated during locked at a specified setting.

Following tested a prototype twin-fuselage release at about 40,000 feet, the towed glider that could lead to glider would launch a booster rocket rockets being launched from into an optimal trajectory to place pilotless aircraft at high altitudes – its payload into low Earth orbit. a technology application that could The glider was built primarily significantly reduce the cost and with commercial-off-the-shelf improve the efficiency of sending components, but some parts were small satellites into space.
