Development of load cells for a 6 degree of freedom (6-DOF) thrust measurement system (TMS)

The National Aeronautics and Space Administration Shared Services Center (NASA/NSSC) has issued a Special Notice for the development of load cells for a six-degree of freedom (6-DOF) thrust measurement system. The opportunity is specifically targeted at developing specialized load cells for liquid rocket engine hot fire testing at NASA Marshall Space Flight Center. NASA intends to award a contract under FAR 13.106-1(b)(1)(i), with an initial indication of Interface, Inc. as the potential sole source provider. The notice is categorized under NAICS Code 334513 for Instruments and Related Products Manufacturing, focusing on measuring and controlling industrial process variables. The procurement will utilize commercial items and services under FAR Part 12 and Part 13.

Contractors interested in this opportunity must submit their capabilities and qualifications in writing by 12:00 p.m. Central Standard Time on May 15, 2025. The project requires the development of eight load cells: seven capable of measuring at least 25,000 lbf and one capable of measuring at least 100,000 lbf, with stringent technical specifications. The load cells must meet precise performance parameters, including operating temperatures from -65 to +200 degrees Fahrenheit, vibrational frequency tolerance up to 26 kHz, and a maximum weight of 12 lbm. The period of performance runs from May 1, 2025, through October 1, 2025, with a 12-week delivery timeline after the order date. Deliverables will be shipped to Central Receiving at Marshall Space Flight Center in Huntsville, Alabama. While the notice suggests a potential sole source procurement, NASA retains sole discretion on conducting a full and open competitive process, and oral communications are not acceptable in response to this notice.
