Federal contract award
80LARC19F0042
TD-FAST (TIME DOMAIN FAST ACOUSTIC SCATTERING TOOLKIT) APPLICATION AND ENHANCEMENT. ACCURATE AND EFFICIENT HIGH-FIDELITY NOISE PREDICTION TOOLS ARE CRITICAL TO THE DESIGN AND ASSESSMENT OF CONVENTIONAL AND UNCONVENTIONAL AIRCRAFT CONFIGURATIONS. THE PURPOSE OF THIS RESEARCH IS TO FURTHER DEVELOP, IMPLEMENT AND VALIDATE AN EFFICIENT HIGH-FIDELITY TIME DOMAIN ACOUSTIC SCATTERING PREDICTION TOOL THAT IS CAPABLE OF CONSIDERING A COMPLETE AIRCRAFT, COVERING A FULL FREQUENCY RANGE OF INTEREST WITHIN A SHORT TURN-AROUND TIME. TIME DOMAIN ACOUSTIC SCATTERING PREDICTION CAPABILITIES HAVE SOME DISTINCT ADVANTAGES OVER FREQUENCY DOMAIN APPROACHES. MOST NOTABLY, SCATTERING SOLUTIONS AT ALL FREQUENCIES ARE OBTAINED WITHIN ONE SINGLE COMPUTATION. IN ADDITION, BROADBAND NOISE SOURCES AND TIME DEPENDENT TRANSIENT SIGNALS CAN BE SIMULATED AND STUDIED. THE TIME DOMAIN APPROACH ALSO COUPLES NATURALLY WITH NONLINEAR COMPUTATIONS WHERE MANY FREQUENCIES ARE GENERATED. FINALLY, WITH RECENT ADVANCES IN MULTI-LEVEL ALGORITHMS, COMPUTATIONAL COMPLEXITY CAN BE GREATLY REDUCED, MAKING IT FEASIBLE FOR ROUTINE APPLICATION AT MID TO HIGH FREQUENCIES WITH REDUCED RESOURCE REQUIREMENTS. THIS TASK CONTINUES THE DEVELOPMENT OF THE TIME DOMAIN FAST ACOUSTIC SCATTERING TOOLKIT (TD-FAST) PREVIOUSLY DEVELOPED UNDER NIA TASK ORDER 80LARC18F0106.
