Helicopter Noise Reduction Topic Of Winning Entry
NASA's Aeronautics Research Mission Directorate, in cooperation
with the American Helicopter Society (AHS) has selected the first
winner of the Lichten Internship Award... a study that could lead
to quieter whirlybirds in the skies over an airport near you in the
future.
Eric Greenwood II from the University of Maryland, University
Park, was selected based on his paper, "Helicopter External Noise
Radiation in Turning Flight: Theory and Experiment," according to a
NASA.
The award supports NASA's goal of enhancing the education of
qualified US engineering students in fields of interest to the
agency's aeronautics program, including fundamental research,
particularly in subsonic rotary wing technologies.
Greenwood will receive an eight-week, NASA-sponsored internship
that will be split between Ames Research Center in Moffett Field,
CA and Langley Research Center in Hampton, VA. Both centers
actively research helicopter noise as part of NASA's Subsonic
Rotary Wing Project. Greenwood will spend the summer participating
in NASA rotary wing science and technology projects.
The challenge of the Subsonic Rotary Wing 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.
The Supersonics Project is a broad-based effort designed to
develop knowledge, capabilities and technologies that support all
vehicles that fly in the supersonic speed regime.
Greenwood graduated from the Rochester Institute of Technology
in Rochester, NY with a Bachelor of Science degree in mechanical
engineering (aerospace option), in 2005. He has specialized in
rotorcraft acoustics for his graduate program in aerospace
engineering.
