NASA SELECTS PRATT & WHITNEY AIRCRAFT FOR TECHNOLOGY DEVELOPMENT CONTRACT
CLEVELAND, OH -- NASA Lewis Research Center has awarded a $27 million five-year contract to United Technologies Corporation, Pratt & Whitney Aircraft of East Hartford, CT, to develop critical propulsion and engine noise reduction technologies for the next generation of U.S. subsonic commercial engines.
Under the cost-reimbursement-without-fee contract, critical advancements will be pursued to reduce nitrogen oxide emissions by 70 percent and expected future engine noise levels. Research also will be conducted on engine technologies that will improve fuel efficiency by eight percent and direct operating costs by three percent.
Work to be performed under the propulsion category includes low emission combustor, validated aeroelastic codes for turbomachinery, design codes for hi-bypass ducts, advanced seals, lightweight affordable engine structures and advanced controls and accessories.
Areas of development for engine noise reduction technology include aerodynamic and aeroacoustic prediction code development and fan/nacelle noise reduction concept design and testing.
Contract results are expected to provide the technical data to address pending emission and noise regulations that will impact the large engines (20,000 to 100,000 lb. thrust) that will enter commercial services in the year 2000 to 2005.
The company will develop and demonstrate these technologies at their facilities in East Hartford as well as at Lewis.
