About this file
This statement of work outlines requirements for vibration testing and post-vibration cryogenic testing of a 20W at 20K cryocooler for NASA. The contractor will design and fabricate a vibration test fixture for the cryocooler components and conduct vibration testing per the GEVS-SE specification. Structural analyses will ensure the cryocooler can withstand testing. The contractor will write test plans and procedures, perform individual or simultaneous vibration tests of cold and warm modules, and conduct post-test verification including leak checks and functional cryogenic testing. The contractor will analyze test data, submit summary reports, and support monthly teleconferences. Planned dates include fixture design from October to December 2024, repackaging and vibration testing from January to March 2025, with a summary report in April 2025 and post-vibration testing from April to June 2025 before shipping the cryocooler to NASA Glenn Research Center in June 2025.
The related federal contract opportunity is a sole source synopsis for this vibration and post-vibration verification testing of the 20W 20K cryocooler issued by the National Aeronautics and Space Administration Glenn Research Center.

11/28/23 Statement of Work Vibration Test
1.0 Shipment and Vibration Test
Following the NASA Characterization and Endurance Test (currently scheduled to conclude in January 2025) for the 20W at 20K cryocooler, the contractor shall perform vibration and post-vibration verification testing for the cryocooler. Vibration testing is the one aspect that needs to be added to raise the technology readiness level from 5 to 6.
1.1 Vibration testing of the 20W 20K Cryocooler shall be conducted per GEVS-SE, General Environmental Verification Specification for STS and ELV Payloads.
1.2 The contractor shall design and fabricate a vibration test fixture(s) and install the hardware to couple the cryocooler components (Three compressors, five recuperators, one turboalternator, tubing, valves) to vibration fixtures. This fixture will serve as support for the cryocooler for all future operations.
1.3 The contractor shall provide structural analyses to ensure that the structural design of the cryocooler is adequate to survive the GEVS-SE specification. The analysis shall be delivered to NASA.
1.4 The contractor shall write a vibration test plan and procedures for the cryocooler for NASA’s approval.
1.5 The contractor shall perform vibration testing for the cold and warm modules. This may be completed individually or simultaneously.
1.6 The contractor shall perform a leak, proof pressure, and spin test to verify cryocooler survivability following the three single-axis vibration tests (x, y, and z).
1.7 The contractor shall reduce, analyze, and interpret the vibration test data and write a summary report of the cryocooler’s survivability of the vibration testing. This report shall be delivered to NASA,
1.8 The contractor shall perform a functional test post-vibrational testing, verifying cryocooler performance at cryogenic temperatures per the test matrix in Figure 1. A test data report shall be deliver to NASA.
1.9 The contractor shall support NASA in monthly telecons, beginning with Award Authority to Proceed.
1.10 The contractor shall document assumptions and testing processes in the proposal relevant to the cryocooler vibration fixture fabrication, vibration test, and post-vibrational cryogenic test.
The planned dates for this activity are as follows. These dates are nominal and subject to change based on hardware availability.
Design and fabricate Cryocooler Test Fixture – (Oct-Dec 2024) Re-Package Cryocooler for Vibration Testing, Conduct Vibe Testing – (Jan-Mar 2025) Summary Report of Cryocooler Vibration Testing (April 2025) Post-vibrational thermodynamic performance testing (April-June 2025) Ship Cryocooler to GRC – (June 2025)
