  IGF::OT::IGF OTHER FUNCTION - DURING INITIAL DESIGN STUDIES, PARAMETRIC VARIATION OF VEHICLE GEOMETRY IS ROUTINE. IN ADDITION, ROTORCRAFT ENGINEERS TRADITIONALLY USE THE WIND TUNNEL TO EVALUATE AND FINALIZE DESIGNS. CORRELATION BETWEEN WIND TUNNEL RESULTS AND FLIGHT TESTS, WHEN NOT GOOD, HAVE BEEN OFTEN ATTRIBUTED IN PART TO UNCERTAINTY IN BLOCKAGE CORRECTIONS. ESTIMATION OF ROTOR BLOCKAGE IS SIGNIFICANTLY MORE COMPLEX THAN BLUFF BODY CORRECTIONS AS THE CORRECTION DEPENDS ON OPERATIONAL CHARACTERISTICS SUCH AS ROTOR RPM AND THRUST PRODUCED. THIS PROPOSAL OFFERS TO DEVELOP AN INTEGRATED DESIGN ENVIRONMENT (IDE) WHICH CAN SIMULATE A COMPLETE ROTORCRAFT WITH OR WITHOUT WIND TUNNEL WALLS INCLUDING ALL THE FACILITY EFFECTS. AT THE HEART OF THE INNOVATION ARE: 1. AN AUTOMATED HYBRID GRID GENERATOR. (VISCOUS GRIDS NEAR THE BODIES AND UNSTRUCTURED CARTESIAN GRID EVERYWHERE ELSE) 2. A ROBUST AND ECONOMICAL INCOMPRESSIBLE FLOW SOLVER FOR THE ENTIRE SYSTEM OF GRIDS. 3. MOMENTUM SOURCE BASED ROTOR MODEL THAT IS SUITABLE AND ECONOMICAL FOR SIMULATING CONFIGURATIONS WITH MULTIPLE ROTORS. IN PHASE I, THE PROOF-OF-CONCEPT DEVELOPED USED UNSTRUCTURED CARTESIAN GRID FOR THE MODEL AND WIND TUNNEL. IN PHASE II, THE TOOL WILL BE EXTENDED TO HYBRID GRID WITH VISCOUS GRID NEAR SOLID SURFACES AND WILL INCLUDE SEVERAL TOOLS INCLUDING A SIMPLE CAD LIKE GEOMETRY MANIPULATION TOOL AND PRE- AND POST-PROCESSING TOOLS ALL INTEGRATED IN ONE ENVIRONMENT TO FACILITATE EASE OF USE. POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 1500 CHARACTERS, APPROXIMATELY 150 WORDS) NASA'S INTEREST IN CIVIL ROTORCRAFT RESEARCH PROMPTS FOR A COMPUTATIONAL TOOL WHICH HAS AN INTEGRATED DESIGN ENVIRONMENT THAT IS EASY TO LEARN AND BE ROBUST AND COMPUTATIONALLY EFFICIENT. THE PROPOSED DESIGN TOOL ACCOMPLISHES THIS GOAL, ESPECIALLY IN AREAS WHERE GEOMETRIC DESIGN CHANGES ARE BEING CONSIDERED AND WIND TUNNEL TESTING IS INTEGRAL TO THE DESIGN STUDY. THE TOOL CAN BE EFFECTIVELY USED FOR ROTORCRAFT AND V/STOL AIRCRAFTS WHERE QUANTIFICATION OF PARAMETRIC VARIATION IN THE DESIGN IS ESSENTIAL FOR SUCCESS.

  IGF::OT::IGF OTHER FUNCTIONS - IN THIS HIGHLY INTERCONNECTED WORLD, TRANSPORTATION SYSTEMS MUST FEATURE INCREASED FLEXIBILITY AND SHORTER DOOR-TO-DOOR TRIP TIMES TO BE SUCCESSFUL. SHORTER DOOR-TO-DOOR TRIP TIMES REQUIRE AN INCREASED USAGE OF ROTARY WING AND RUNWAY INDEPENDENT V/STOL TECHNOLOGY. ONE OF THE LIMITING FACTORS TO THE INCREASED ADOPTION OF THIS TECHNOLOGY FOR PROVIDING FEEDER SERVICE TO MAJOR HUBS IS THE LIMITED UNDERSTANDING OF HIGH-VOLUME TERMINAL AREA OPERATIONS. SEVERAL IMPORTANT ISSUES ARE ASSOCIATED WITH ROTARY WING AND RUNWAY INDEPENDENT V/STOL AIRCRAFT, INCLUDING SEVERE AERODYNAMIC INTERACTIONS DURING TAKE-OFF, TRANSITION AND LANDING. THERE IS ALSO THE POSSIBILITY THAT THE AERO-ACOUSTIC ENVIRONMENT GENERATED IN THE TERMINAL AREA MAY CAUSE DAMAGE TO BUILDINGS, UNSAFE WORKING CONDITIONS FOR GROUND PERSONNEL, OR UNACCEPTABLE NOISE LEVELS TO SURROUNDING COMMUNITIES. THE SUCCESS OF COMMERCIAL V/STOL TRANSPORTATION IS PREDICATED ON BEING ABLE TO ESTABLISH TECHNICAL FEASIBILITY, SOCIETAL ACCEPTANCE AND ECONOMIC VIABILITY. THE PROPOSED AERO-ACOUSTIC TOOL FOR TERMINAL AREA OPERATIONS OFFERS A SIMULATION CAPABILITY TO DESIGN ENGINEERS TO MAKE INFORMED DECISIONS BASED ON TECHNICAL (OPERATIONS AND HANDLING NEAR A TERMINAL), SOCIETAL (ACOUSTIC FOOTPRINT) AND ECONOMIC CONSIDERATIONS (PERFORMANCE) THAT INCLUDES THE INTERACTIONAL AERODYNAMICS BETWEEN THE AIRCRAFT AND ITS SURROUNDINGS. THE DESIGNERS AND OPERATORS OF ROTARY WING AND V/STOL AIRCRAFTS WILL USE THE TOOL TO EVALUATE, ENHANCE AND IMPLEMENT MORE EFFICIENT AND SAFE TERMINAL AREA OPERATION GUIDELINES. PHASE I WILL DEVELOP THE PROOF-OF-CONCEPT OF THE SIMULATION TOOL AND USE A TILT-ROTOR AND A CANDIDATE TERMINAL UNDER DIFFERENT WIND CONDITIONS TO DEMONSTRATE ITS USEFULNESS. IN PHASE II, THE TOOL WILL BE EXTENDED TO MANEUVERING ROTARY WING AND V/STOL AIRCRAFTS. IN ADDITION, IT WILL BE INTEGRATED WITH A GRAPHICAL USER INTERFACE (GUI) FOR EASE OF USE.
