NASA's Aeronautics Research Mission Directorate has amended its NASA Research Announcement to solicit additional research proposals. The Research Opportunities in Aeronautics 2007 has been amended to include new topics in support of the Subsonic Rotary Wing Project.
With the amendment, the Subsonic Rotary Wing Project encourages proposals that advance the state-of-the-art in engine compressor technology, transmission noise modeling, low-frequency noise effects and rotorcraft icing methodology.
The challenge of the project is to develop validated physics-based multidisciplinary design and analysis tools for rotorcraft, integrated with technology development, enabling rotorcraft with advanced capabilities to fly as designed for any mission. Meeting this challenge will require innovative technologies and methods, with an emphasis on integrated, multidisciplinary, first-principle computational tools specifically applicable to the unique problems of rotary wing aircraft.
NASA plans to announce additional research topics in other project areas in the near future. For updates, visit NASA's Research Opportunities Web site at:
