Lessons Learned – Building 4777 Impeller Tip Failure
Year: 1998
Abstract: Description of Driving Event:
Water flow pump impeller blade tips failed during testing at MSFC's Inducer Test Loop (ITL). All three inducer tips were discovered missing during inspection of the pump. An investigation team determined that impeller tip failure was caused by degradation of aluminum impeller material (caused by anodizing and/or heat treat) and/or high impeller dynamic flow forces.
