Mr. Ishii is JAXA's technical lead for noise modeling research and briefed this work as part of JAXA's Distributed and Revolutionarily Efficient Air Traffic Management System (DREAMS) project where they are developing noise abatement concepts for future air traffic management systems. Aviation Systems Division researchers presented terminal area research activities on the Efficient Descent Advisor (R. Coppenbarger) and Terminal Sequencing and Spacing (R. Johnson), as well as research aimed at developing computationally efficient noise modeling algorithms for trajectory optimization, including a Google Earth-based tool to evaluate aircraft noise impacts (B. Sridhar and N. Chen). The NASA/JAXA collaboration in this area will be focused on developing a computationally efficient aircraft noise model considering the effect of meteorological conditions on noise propagation. It was agreed that NASA and JAXA have a common interest in optimizing trajectories to minimize noise and emissions in the presence of increasing traffic volume, and that this work is longer-term in nature. Both groups will brainstorm further within their organizations to identify specific collaborative opportunities and exchange ideas at a future meeting. (POC: Rich Coppenbarger) + Back to Top
