The Impact of Active Aeroelastic Wing Technology on Conceptual Aircraft Design

Abstract : Active Aeroelastic Wing (AAW) Technology represents a new design approach for aircraft wing structures. The technology uses static aeroelastic deformations as a net benefit during maneuvering. AAW is currently% being matured through a flight research program however, transition of the technology to future systems will require educating designers in multiple disciplines of this new design approach. In order to realize the full benefits of AAW, aeroelastic effects will need to be accounted for from the beginning of the design process. Conceptual design decisions regarding parameters such as wing aspect ratio, wing thickness-to-chord ratio (tic), and wing torque box geometry may be influenced, if designers choose to utilize AAW. This paper presents recent efforts in developing conceptual aircraft design guidance for AAW technology and identifies improvements to the design process that could facilitate future AAW design applications. This process involves using results from aeroelastic design methods, typically used in preliminary design, with conventional conceptual design methods. This approach will allow aeroelastic effects to be considered in making conceptual design decisions.
