Description

NASArsquo;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 AVECrsquo;s proposal ldquo;Design Cycle Modeling Tool for Wing-Strut Junction Flow Noiserdquo; addresses a technology analysis gap in the development of a leading airframe concept, the Transonic Truss Braced Wing (TTBW) aircraft. The aeroacoustic signatures of the large bracing strut and jury member features of this configuration need to be studied with appropriate modeling to enable design cycle input based on far field noise estimates of these features. We propose to produce a database of hemisphere noise levels (1/3 octave band) using PowerFLOW CFD, with an accompanying model based on machine learning for design cycle trades of this noise source. In addition to gaining valuable insight into the aerodynamics and aeroacoustics of wing-strut junction flows, Phase I will conclude with a demonstration of this model.
