99--TECHNOLOGY TRANSFER OPPORTUNITY FLOW CONTROL DEVICES TWO FLUIDICOSCILLATORS WITH NO MOVING PARTS OPTIMIZE FLOW CONTROL FOR BETTER SYSTEM PERFORMANCE

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 develops innovative technologies to control fluid flow in ways that willultimately result in improved performance and fuel efficiency. Often called as fluidicoscillators, sweeping jet actuators or flip flop oscillators, these flow control deviceswork based on the Coanda effect. They can be embedded directly into a control surface(such as a wing or a turbine blade) and generate spatially oscillating bursts (or jets)of fluid to improve flow characteristics by enhancing lift, reducing drag, or enhancingheat transfer. Recent studies show upto a 60% performance enhancement with oscillators.NASA offers two new fluidic oscillator designs that address two key limitations of theseoscillators: coupled frequency-amplitude and random oscillations. One oscillatoreffectively decouples the oscillation frequency from the amplitude. The other designenables synchronization of an entire array. The new oscillators have no moving partsoscillation, decoupling, and synchronization are achieved entirely via internal flowdynamics.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: [email protected], or phone: 757-864-5055. Please indicate thedate and title of the FBO notice and include your company and contact information.RTI is responsible for aggregating and acknowledging all responses. These responses areprovided to members of NASA Langleys Innovative Partnerships Office within the SRO forthe purpose of promoting public awareness of our technology products, and conductingpreliminary market research to determine public interest in and potential for futurelicensing opportunities. If direct licensing interest results from this posting, SRO willfollow the formal licensing process of posting in the Federal Register as required. Nofollow-on procurement is expected to result from responses to this Notice.
