99--TECHNOLOGY TRANSFER OPPORTUNITY MULTI-FUNCTIONAL COMPOSITE AND HONEYCOMBPANELS

NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. THE TECHNOLOGY: Scientists at NASA Langley Research Center designed honeycomb panels with recessed areas in the core that lower the acoustic radiation efficiency. Since the recesses would have reduced the strength of the composite construction as well, Langley researchers created a variety of embedded reinforcing sub-face sheets and domed variations of those sheets to carry the required loads. The sandwich composite construction comprises interior and exterior panels that capture an internal honeycomb core. The honeycomb core, instead of being full thickness across its entire area, incorporates a pattern of recesses to create areas of reduced stiffness. The reduced stiffness forces the normally supersonic waves in the structure to drop to subsonic speeds, thereby lowering the acoustic radiation efficiency of the composite structure in those areas. To make up for the loss in stiffness created by the recesses, various reinforcement schemes are employed in the recesses. A side effect of the reinforcements is that they create embedded double-wall cavities that contribute to the sound attenuation character of the design. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/ . These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development OSACB for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
