This sensitivity study is focused on understanding the rate at which blade thickness can affect the risk of high-cycle fatigue failure in an impeller of a centrifugal compressor. The investigated Ti-alloy impeller serves to compress and deliver feed air into the combustion chamber of the jet-engine...
