Techsburg selected for NASA Phase II SBIR contract entitled “Design Cycle Prediction Software for Wing-Strut Junction Flow Noise”

Wing-Strut Broadband Acoustic Model


NASA’s Advanced Air Transport Technology Project has worked with industry over the last decade to develop airframe/propulsion concepts and associated technologies to enable transformative air travel for future generations. Techsburg and AVEC’s proposal “Design Cycle Prediction Software for Wing-Strut Junction Flow Noise” addresses a technology analysis gap in the development of a leading airframe concept, the Transonic Truss Braced Wing (TTBW) airliner. The aeroacoustic signatures of the large bracing strut and jury member features of this configuration need to be captured in reduced-order modeling tools to enable design cycle trade studies/optimization of far field noise due to the wing/strut junction noise source. Building on Phase I success, we propose to train an artificial neural network (ANN) model of this noise source using PowerFLOW lattice-Boltzmann method (LBM) computational aeroacoustic simulations. Phase II will conclude with delivery of the reduced-order software tool Wing-Strut Broadband Acoustic Model, “WiSBAM”.
