IGF::OT::IGF A NOVEL ACTUATION CONCEPT PREVIOUSLY USED FOR TRAILING EDGE TAB CONTROL IS TO BE EXTENDED FOR USE IN SPANWISE CAMBER CONTROL FOR ENHANCED AERODYNAMIC PERFORMANCE OF NEXT GENERATION AIRCRAFT DESIGNS. THE KEY FEATURES OF ITS LOW-POWER, TWO-POSITION (BISTABLE) NATURE AND SMALL SIZE PERMIT ITS APPLICATION AS SECONDARY STRUCTURE WITHIN WING ASSEMBLIES, THEREBY ALLOWING FOR FLIGHT-DEPENDENT CUSTOMIZATION OF THE SPANWISE CAMBER TO OPTIMIZE VEHICLE AERODYNAMIC EFFICIENCY. THE PROPOSED PHASE I PROGRAM WILL LEVERAGE PREVIOUS DEVELOPMENT SUCCESS OF THE ACTUATION CONCEPT TO SCALE DESIGN APPLICATIONS FOR ULTIMATE USE ON TRANSPORT-CATEGORY AIRCRAFT, AND PROVIDE RISK REDUCTION VIA DEMONSTRATION WIND TUNNEL TESTS ON A SCALED WING HALF-SPAN MODEL. A BYPRODUCT OF THE SCALING LAW WILL BE ITS INCORPORATION WITHIN A MULTIDISCIPLINARY DESIGN ANALYSIS AND OPTIMIZATION (MDAO) TOOL FOR EASE OF EXPLORATION OF THE ACTUATION FEATURES IN THE CONTEXT OF NOVEL VEHICLE CONFIGURATIONS HAVING FLIGHT CONTROL FOR PERFORMANCE ADJUSTMENT.
