Quiet Performance-Aircraft Propulsion Noise

Safer, cleaner, and quieter aircraft have a competitive advantage in the global market. Improved aircraft propulsion systems are needed for aircraft of all sizes, shapes, speeds, and altitudes so that a commercial air transportation system is accessible to move people and cargo around the world. Reductions in aircraft noise could lead to wider community acceptance, lower airline operating costs where noise quotas or fees are employed, and increased potential for air traffic growth on a global scale. The goal of this subtopic is to support the development and commercialization of tools and technologies to predict, diagnose, and reduce noise from aircraft propulsion systems and components.
