Description: BLOWN AIRFOIL CFD. THIS TASK WILL PERFORM COMPUTATIONAL FLUIDIC DYNAMIC (CFD) ANALYSIS ON A BLOWN WING CONFIGURATION TO DETERMINE AERO-PROPULSIVE PERFORMANCE. DISTRIBUTED ELECTRIC PROPULSION (DEP) ENABLES A HIGH DEGREE OF COUPLING BETWEEN THE AERODYNAMICS AND PROPULSION CHARACTERISTICS OF AIRCRAFT WING SYSTEMS. TIGHT COUPLING OF THESE TWO DISCIPLINES OFFER OPPORTUNITIES TO IMPROVE THE PERFORMANCE AND ACHIEVE CAPABILITIES THAT CAN T BE ACHIEVED WITH ISOLATED WING AND PROPULSION SOLUTIONS. HIGHER-ORDER ANALYSIS USING CFD TOOLS IS REQUIRED TO CAPTURE THESE HIGHLY COUPLED EFFECTS WITH ANALYSIS TOOLS THAT HAVE BEEN CALIBRATED TO VALIDATION DATASETS FROM PRIOR AERO-PROPULSIVE WIND TUNNEL TESTS. ANALYSIS OF SPECIFIC DEP WING SYSTEMS IS DESIRED TO IMPROVE THE STATE OF THE ART TO ACHIEVE VERY HIGH LIFT AT LOW SPEEDS, AT EVEN STATIC CONDITIONS WHILE ENTRAINING FLOW TO MAXIMIZE THE WING LIFTING CHARACTERISTICS. AT THE SAME TIME HIGH CRUISE EFFICIENCY IS DESIRED, ALONG WITH EXCELLENT CONTROL CHARACTERISTICS THROUGHOUT THE FLIGHT ENVELOPE. THIS RESEARCH WILL INVESTIGATE SPECIFIC DEP CONFIGURATION TO BETTER UNDERSTAND THE AERO-PROPULSIVE CHARACTERISTICS. EXISTING ANALYSIS WAS PERFORMED ON A GEOMETRY. THIS CURRENT STATEMENT OF WORK EXTENDS PREVIOUS WORK WITH MODIFICATIONS TO THE LOCATIONS AND SHAPE OF THE PROPULSORS, SLOT LOCATIONS, AND WING.
