Helping to establish failure thresholds and service life limits, high cycle fatigue (HCF) testing is an integral part of our aerospace engine qualification programs. Our unique, world-class capabilities enable us to handle everything from small sub-components to the largest fan blades in service today.
High vibrations conditions of airfoils during operation can impact the structural integrity of a test specimen, which makes HCF testing indispensable. Individual metallic and future advanced material turbine blades or segments of a bladed disk are tested in the natural resonance frequency range until crack initiation. Our equipment allows us to run a very high number of cycles in a short amount of time, simulating a components' service life. Our HCF testing service portfolio also includes the ability to carry out strain gauge calibration on instrumented airfoils.
Performing High Cycle Fatigue Testing (HCF)
During HCF testing, individual turbine blades (or blade samples) are cycled at an extremely high rate to mimic their natural operating frequency. Once cracking starts to occur, the failure cycle count is recorded, and the product is analyzed for performance characteristics and durability criteria.
We understand the unique environments and challenges that airfoils and aerospace engine components face. To better support your testing program, we offer a range of options for high cycle fatigue testing, including testing at temperatures up to 1200 C, sample notching and machining services, fixture and clamp design, and specialist test methods.
