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.

Official solicitation and documents

The full solicitation, any attachments, and the actual submission instructions live on the official listing, not on this page. Oppward summarizes public record data; it does not host or mirror the source documents.

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
