AI Contract Overview

Show more

NASA is offering a technology transfer opportunity for the Supersonic Spike Diffuser (SSC-TOPS-10), an innovative propulsion system developed at the Stennis Space Center that significantly enhances vacuum pumping efficiency in supersonic gas flows. Unlike traditional second-throat diffusers that suffer from high Mach number shock losses, this new spike diffuser design reduces both core flow Mach number and flow deflection in a Pareto-efficient manner, achieving approximately double the pumping performance while requiring only about 25% of the length of conventional designs. The technology enables substantially lower vacuum pressures at given feed pressures and mass flows by allowing the use of higher-expansion-ratio driving nozzles, making it ideal for applications requiring compact, high-efficiency vacuum systems. License rights—exclusive or nonexclusive and potentially restricted to specific fields of use—are available without any accompanying NASA funding, and interested companies must submit applications through NASA’s ATLAS system by the deadline of August 10, 2027. This notice serves solely to gauge market interest and does not lead to any procurement or direct government acquisition.

Full Description

Show more

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:  


Standard cylindrical and second-throat diffusers allow supersonic gas flows to expand within their walls and pull a vacuum on any upstream void. However, the high-Mach-number shock reflections that occur in the center of the plume create substantial losses and result in an inefficient pumping process. Centerbody diffuser designs provide an improvement by reducing the maximum Mach number of the core flow, but also increase the number of oblique shocks in the system by introducing multiple turns into the system. A new type of spike diffuser recently developed by NASA Stennis Space Center is able to provide approximately double the pumping performance of second-throat diffusers via Pareto-efficient reduction of both core Mach number and flow deflection. This enables substantially lower vacuum pressures to be achieved for a given feed pressure/mass flow via the use of higher-expansion-ratio driving nozzles. Spike diffusers are also spatially compact, requiring only ~25% of the length of second-throat designs. 


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/SSC-TOPS-10  


If 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. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ 


These responses are provided to members of NASA’s Technology Transfer Program 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. No follow-on procurement is expected to result from responses to this Notice.
