NASA Langley Research Center in Hampton, VA solicits interest from companiesinterested in obtaining license rights to commercialize, manufacture and market thefollowing technology. License rights may be issued on an exclusive or nonexclusive basisand may include specific fields of use. THE TECHNOLOGY: NASA Langley researchers have developed a novel noise reduction system for jet engines.Aircraft jet engine noise is a major issue for airports, the communities near airports,and, of course, for the jet engine designers. Even with the use of recenthigh-bypass-ratio jet engine designs, noise continues to be a major concern. The presentinnovation represents a significant advancement to the concept of using mechanicallyfixed chevrons on the trailing edge of jet engine nozzles to reduce noise. While theeffect of chevrons on noise reduction is well known, commercial implementation has beenlimited. Unfortunately, the turbulence created with the chevrons, while useful forreducing noise upon takeoff, serves to reduce efficiency during cruising. The presentinnovation is a simple noise reduction system with effects similar to that of chevrons,yet it is active and controllable to maximize noise reduction while maintainingefficiency.To express interest in this opportunity, please respond to Sean Sullivan, ResearchTriangle International (RTI), at: NASA Langley Research Center, Strategic RelationshipsOffice (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton,Virginia, E-mail:
