IN RESPONSE TO BOTH ECONOMIC AND ENVIRONMENTAL CONCERNS THE NASA AEROSPACE RESEARCH MISSION DIRECTORATE HAS LED EFFORTS TO DEVELOP NEW TECHNOLOGIES FOR ULTRA-EFFICIENT NEXT-GENERATION AIRCRAFT. MORPHING-WING TECHNOLOGY HAS SHOWN PROMISE TO PROVIDE SIGNIFICANT FUEL-SAVING BENEFITS. HOWEVER IN ORDER TO FULLY TAKE ADVANTAGE OF THIS TECHNOLOGY NEW TIME-CONTINUOUS AEROSTRUCTURAL OPTIMIZATION METHODS THAT PROVIDE ADDITIONAL INSIGHT INTO THE EFFECTS OF WING MORPHING ARE NEEDED. THIS PROJECT PROPOSES THE ANALYTICAL INVESTIGATION OF AEROSTRUCTURAL RELATIONSHIPS THAT PREDICT THE EFFECTS OF WING MORPHING ON FUEL CONSUMPTION AND FACILITATE THE PREDICTION THE OPTIMAL FIXED- AND MORPHING-GEOMETRY AIRCRAFT CONFIGURATIONS THAT MINIMIZE INDUCED DRAG OVER A TIME-CONTINUOUS FLIGHT PROFILE. THE PROJECT WILL CONSIST OF FOUR PHASES INCLUDING THE IDENTIFICATION OF STATIC FUEL-CONSUMPTION RELATIONSHIPS FIXED-GEOMETRY AIRCRAFT OPTIMIZATION MORPHING-WING AIRCRAFT OPTIMIZATION AND VALIDATION AND ASSESSMENT. IT IS ANTICIPATED THAT THIS PROJECT WILL RESULT IN A NEW SUITE OF AERODYNAMIC TOOLS AND ANALYTICAL RELATIONSHIPS THAT WILL PROVIDE INSIGHT INTO THE EFFECTS OF WING MORPHING ON AIRCRAFT EFFICIENCY
