http://www.nasa.gov/centers/armstrong/research/ACTE/#.VH4sQLY-IZ0 NASA's green aviation project, together with the Air Force Research Laboratory (AFRL) and FlexSys, Inc, is one step closer to demonstrating 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. The Adaptive Compliant Trailing Edge (ACTE) is a direct result of 20 years of collaboration between AFRL and FlexSys and the ongoing flight tests will determine if flexible trailing-edge wing flaps can both improve aerodynamic efficiency and reduce airport-area noise generated during takeoffs and landings. In this joint effort, conventional hinged flaps on a modified Gulfstream III business aircraft were replaced with FlexSys’ advanced, shape changing flaps that form continuous bendable and twistable surfaces. The first ACTE flight was successfully completed on November 6 at NASA’s Armstrong Flight Research Center, and was followed by additional successful flights. The testing will continue over the next several months.
