NASA's Armstrong Flight Research Center (AFRC) is seeking proposals for the procurement of a Cryogenic Transportation Trailer designed for the delivery of liquid nitrogen (LN2) and gaseous nitrogen (GN2) for thermal testing purposes. The trailer must have a usable capacity between 4,500 and 6,000 gallons, with the capability to store, transport, and dispense LN2 and GN2, while adhering to specific operational parameters and safety regulations. This procurement is critical for enhancing AFRC's capabilities in experimental flight research, ensuring compliance with ISO 9001 quality standards and relevant ASME codes. Interested vendors must submit their proposals by 12:00 PM Pacific on Thursday, March 13, 2025, to Melissa Newell at melissa.newell@nasa.gov, and are encouraged to address any questions by March 7, 2025.
