Linearized FUN3D for Rapid Aeroelastic and Aeroservoelastic Design and Analysis

The proposed effort is highly relevant to NASA's on-going and future projects within NASA's fixed wing project under the Fundamental Aeronautics Program. NASA's fixed wing project involves several non-conventional design concepts such as the Truss-Braced Wing (TBW), the Blended Wing Body (BWB) and the Supersonic Business Jet (SBJ). Because of the BWB's flying-wing-type and the SBJ's slender fuselage designs, these designs are prone to the BFF (Body Freedom Flutter) problem. In addition, it is expected that the gust loads on the high aspect ratio wing of the TBW configuration will be one of the critical design loads. The proposed work will offer a computational tool to the NASA designers for early exploration of technologies and design concepts that exploit the trade-off between the passive and active approaches for mitigating the potential aeroelastic problems associated with those non-conventional configurations. It thus can be seen that through the research planned to be conducted during Phase I and II of this effort, NASA's Fundamental Aeronautics Program will benefit significantly. FunZEUS developed in Phase I and II of this effort can be effectively applied to many categories of flight vehicles including X-56A MUTT, X-48B blended wing-body, joined-wings, sub/supersonic transports, morphing wing aircraft, space planes, reusable launch vehicles, and similar future flight vehicle concepts pursued by NASA, thereby largely expanding NASA's technology portfolio.

The potential market for FunZEUS includes organizations involved in air vehicle design, aircraft flight test centers, airframers, aircraft analysis, commercial, business jet and military aircraft manufacturers, and organizations that maintain current air vehicles. ZONA will market FunZEUS to the aerospace industry, which includes government agencies, private industry, and universities. More »
