THE FOLLOWING TASK DESCRIPTIONS ARE IN SUPPORT OF THE SYSTEMS INTEGRATION, ASSESSMENT & VALIDATION DISCIPLINE OF THE NASA FUNDAMENTAL AERONAUTICS SUPERSONICS PROJECT. THE OVERALL EFFORT IS FOCUSED ON IMPROVING THE DESIGN CYCLE TIME AND UNCERTAINTY IN LOW BOOM SUPERSONIC VEHICLE DESIGN. THE NEED FOR MULTI-FIDELITY DESIGN AND ANALYSIS TOOLS FOR SONIC BOOM WILL ENABLE IMPROVED CYCLE TIME WITH MORE ACCURATE PREDICTIONS OF OVERALL SONIC BOOM LEVELS. THE CURRENT DESIGN PROCESS IS BASED ON LINEAR AERODYNAMIC AND BOOM ANALYSIS METHODS. STEPS ARE BEING MADE TO GENERATE GEOMETRY FROM THESE LINEAR DESIGN METHODS TO ENABLE THE ABILITY TO RAPIDLY TURN AROUND COMPUTATIONAL FLUID DYNAMIC (CFD) PRESSURE PREDICTIONS FOR USE IN IMPROVED SONIC BOOM PROPAGATION METHODS. THE NEEDED WORK IS IN THE INTEGRATION INTO THIS PROCESS OF CFD GRIDDING AND ANALYSIS WITH THE IMPROVED BOOM PROPAGATION METHODS. THE GOALS OF THIS TASK ARE: TO DEVELOP STRATEGIES TO GENERATE CONFIGURATION-DEPENDENT TARGET AREA DISTRIBUTION THAT IS EASIER TO BE REALIZED BY A PRACTICAL CONFIGURATION. TO EXPLORE PRACTICAL CFD-BASED DESIGN CAPABILITIES FOR SUPERSONIC CONFIGURATION DESIGN. TO EXPLORE WAYS TO INTEGRATE PROPULSION SYSTEM DESIGN INTO LOW-BOOM AND LOW-DRAG DESIGN PROCESS FOR SUPERSONIC CONFIGURATIONS.
