Abstract

An overview of the collaborative research conducted between NASA and Industry, Other Government Agencies and Universities on Ultra High Bypass Ratio cycle propulsion concepts from the 1970s to the present will be presented.  The current research activities within the Ultra High Bypass Partnership under the Subsonic Fixed Wing Project are described, with a focus on the collaboration between NASA and Pratt and Whitney on the Geared Turbofan Engine Program to highlight the positive impact of collaboration for both NASA and the Industry partner.

Biography

Christopher Hughes received a BS in Aeronautical and Astronautical Engineering from Ohio State University and a MS in Mechanical Engineering from the University of Toledo.  His 27 year career at Glenn has been in entirely in the field of propulsion aerodynamics and acoustics.  He has been the Project Manager, Principle Investigator and/or Lead Research Engineer on twenty one separate wind tunnel research projects to investigate and development technology to enhance the aerodynamic performance and reduce the acoustic noise signature of advanced aircraft propulsion concepts including high speed turboprop, counter rotation propfan, and high and ultra high bypass ratio turbofan engine cycles.  He is currently the Manager for the Ultra High Bypass Engine Technology Demonstration and Integration Validation Partnership Element of the Subsonic Fixed Wing Project in the Fundamental Aeronautics Program.
