Special Notice NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market the High-Fidelity Sonic Boom Propagation Tool (LAR-TOPS-329). This tool, developed by NASA's Technology Transfer Program at the NASA Langley Research Center, predicts and mitigates sonic boom levels for supersonic aircraft. It incorporates atmospheric and terrestrial effects, handles aircraft trajectories and maneuvers, and offers an updated approach to accurately predict sonic boom ground signatures. The tool has potential applications in the design and development of next-generation supersonic aircraft, enabling pilots and operators to plan flight paths to reduce noise footprints. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). For more information, visit the NASA Technology Transfer Portal. No follow-on procurement is expected from this notice.
