RESEARCH IS PROPOSED FOR THE DEVELOPMENT OF A STATE-OF-THE-ART COMPUTATIONAL AEROELASTIC TOOL. THIS TOOL WILL INCLUDE VARIOUS LEVELS OF FIDELITY AND THE ABILITY TO PERFORM COMPUTATIONAL UNCERTAINTY QUANTIFICATION FOR DATA-DRIVEN RISK ANALYSIS AND CERTIFICATION. A NUMBER OF NOVEL REDUCED-ORDER IN TIME METHODS WILL BE IMPLEMENTED INTO THE CODE ALLOWING FOR EFFICIENT AND ACCURATE AEROELASTIC SIMULATION WHICH WILL ENABLE BOTH THE EXPLORATION OF COMPLEX PHYSICS, POINT DESIGN AND FAST GENERATION OF "TRAINING DATA" FOR REDUCED ORDER SPATIAL AEROELASTIC MODELS. THE VARIOUS LEVELS OF FIDELITY AVAILABLE IN THE CODE FOR AEROELASTIC MODELING WILL RANGE FROM CFD-BASED (BOTH GRID-BASED AND A NOVEL PARTICLE-BASED METHOD) SIMULATION TO REDUCED-ORDER AEROELASTIC MODELS BASED UPON VOLTERRA SERIES REPRESENTATIONS AND PROPER ORTHOGONAL DECOMPOSITION (POD). THE APPLICATION OF THE PROPOSED INNOVATIONS SPANS THE RANGE OF FLIGHT, FROM HIGH-SPEED TRANSPORT VEHICLES, TO SMALL-SCALE, FLAPPING MICRO-AIR VEHICLES. ANTICIPATED RESULTS INCLUDE 1) THE FURTHER VALIDATION AND IMPLEMENTATION OF THE PROPOSED NOVEL TIME-REDUCED ORDER MODELS INTO THE EXISTING ASTE-P SOLVER FRAMEWORK (WHICH ALREADY INCLUDES THE VARIOUS LEVEL FIDELITY MENTIONED ABOVE), 2) APPLICATION OF THE PROPOSED WORK TO LARGE-SCALE SIMULATION AND COMPARISON WITH EXPERIMENT, AND 3) ADVANCEMENT OF THE STATE OF KNOWLEDGE FOR NONLINEAR PROBLEMS IN AEROELASTICITY IN BOTH THE SUBSONIC, LOW REYNOLDS NUMBER REGIME AND TRANSONIC HIGH REYNOLDS NUMBER REGIME.

THE PROPOSED WORK WILL ESTABLISH HIGH FIDELITY COMPUTATIONAL METHODS AND WIND TUNNEL TEST MODEL IN SUPPORT OF NEW FREEPLAY CRITERIA FOR THE DESIGN, CONSTRUCTION AND CONTROLLED ACTUATION OF CONTROL SURFACES WITH VARYING AMOUNTS OF FREEPLAY AND THEIR AEROELASTIC RESPONSE. THESE METHODS WILL BE VALIDATED WITH WIND TUNNEL AND FLIGHT TEST DATA. IN PHASE I A NONLINEAR COMPUTATIONAL AEROSERVOELASTIC METHODOLOGY WILL BE DEVELOPED FOR FREEPLAY INDUCED FLUTTER/LCO AND GUST RESPONSE. VALIDATION WILL BE ACHIEVED BY COMPARISONS WITH LEGACY AND NEW WIND TUNNEL TEST DATA. IN PHASE II THE METHODOLOGY WILL BE GENERALIZED TO CREATE A MATURE SOFTWARE CAPABILITY FOR CLOSED-LOOP AEROELASTIC SYSTEMS IN THE TRIMMED/UNTRIMMED STATE INCLUDING GUST, STICK OR RANDOM AEROACOUSTIC EXCITATIONS. AN ALL MOVABLE TAIL WING WIND TUNNEL TEST ARTICLE WILL BE DESIGNED AND BUILT WITH VARIABLE FREEPLAY WITH INITIAL TEST EVALUATION COMPLETED IN PHASE I AND A THOROUGH PARAMETER VARIATION DATA SET AND WILL BE DEVELOPED IN PHASE II FOR COMPUTATIONAL CODE VALIDATION IN PHASE II. SUBJECT TO AVAILABLE FUNDING CONSTRAINTS BOTH HIGH SPEED TRANSONIC AS WELL AS SUBSONIC WILL TUNNEL TESTS WILL BE UNDERTAKEN. IN PHASE III THE COMPUTATIONAL METHODOLOGY IN COMBINATION WIND TUNNEL TEST RESULTS WILL BE USED TO SUPPORT THE IMPROVEMENT OF THE CURRENT FAA AND/OR MIL-SPEC FREEPLAY AEROELASTIC RESPONSE CRITERIA. FOLLOWING THE SUCCESSFUL DEMONSTRATION AND VALIDATION OF THE NEW COMPUTATIONAL METHODS, THE METHODOLOGY WILL BE PROPOSED FOR ADOPTION BY FAA FOR COMMERCIAL APPLICATIONS AND THE DOD FOR MILITARY APPLICATIONS WITH THE EXPECTATION THAT ALL MAJOR CIVILIAN AND MILITARY AEROSPACE INDUSTRIES WILL ADOPT THE DESIGN/ANALYSIS METHODOLOGY FOR FREEPLAY INDUCED LCO/FLUTTER PREVENTION.
