Fatigue Life and Structural Durability Assessment

This subcontract focuses on conducting a fatigue life equivalency analysis to assess the structural durability of propellers when transitioning from the C-27J to the HC-130J operational environments. The analysis will utilize Miner’s Rule along with validated stress-life (S-N/E-N) and crack growth data to accurately translate and predict the expected fatigue life of the propellers under differing usage conditions. The work aims to ensure that the propellers meet durability requirements and maintain safety standards throughout their operational lifespan in the new environment. The contract, titled "Fatigue Life and Structural Durability Assessment," is under the Department of Homeland Security's Aviation Logistics Center and is set to be performed in Elizabeth City, with a response deadline of May 23, 2026. It falls under the NAICS code 541620, related to environmental consulting services, and constitutes a subcontract opportunity. The analysis and assessment provided through this contract are critical to support the structural integrity and reliability of the HC-130J aircraft's propeller systems as they undergo changes in their operational context.
