TECHNOLOGY TRANSFER OPPORTUNITY: High-Temperature Single Crystal Preloader (LEW-TOPS-97)

NASA’s Technology Transfer Program 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. NASA provides no funding in conjunction with these potential licenses.THE TECHNOLOGY: Many aerospace vehicles require thermal barriers/seals to minimize the flow of hot gases through interfaces in thermal protection systems and propulsion systems where temperatures can exceed 1200°F. One of the primary challenges is maintaining proper sealing contact at elevated temperatures. To address this challenge, preloading elements in various spring-like forms are often incorporated into or behind a seal to provide the required resiliency. At these elevated temperatures, conventional spring preloaders made from polycrystalline alloys lose strength and can exhibit excessive creep, resulting in a loss of sealing

contact. Glenn innovators have developed new processes to enable the fabrication of preloaders made of single crystal superalloys that can increase the upper limit of thermal seals to greater than 2000°F for short to moderate term applications, and greater than 1800°F for long term applications. These preloaders can be manufactured in a variety of configurations allowing stiffness to be customized for a particular application.To express interest in this opportunity, please submit a license application through NASA’s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/LEW-TOPS-97If you have any questions, please e-mail NASA’s Technology Transfer Program at Agency-Patent-Licensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this SAM.gov notice and your preferred contact information.
