Adaptive Compliant Trailing Edge II Sub-Project (ACTE II)
Project Description
The ACTE II Sub-Project is an experimental flight research joint effort between NASA and the U.S. Air Force Research Laboratory in partnership with FlexSys. This effort aims to demonstrate fuel burn reduction, control of wing aerodynamic load distribution, and community noise reduction through the use of seamless, adaptive flap technology at relevant commercial flight conditions. The ACTE efforts began under the Environmentally Responsible Aviation Project and has continued under the Flight Demonstrations and Capabilities (FDC) Project as the ACTE II Sub-Project.
More »Anticipated Benefits
Flight testing will characterize the ACTE flap's contribution toward reduced fuel consumption that enables reduced engine exhaust emissions. Primary contributions include drag reduction through the use of variable camber technology to optimize performance throughout the flight envelope, and the use of a more efficient wing surface that does not include drag-inducing gaps and edges. Integrating this technology in new aircraft designs has the potential to reduce the structural weight of the wings to further reduce overall fuel consumption and emissions. A secondary benefit is the airframe noise reduction associated with the seamless flap. This attribute of the ACTE flap was evaluated by the Landing Gear Noise Reduction Sub-Project within the FDC Project.
