Blade envelopes Part I: Concept and methodology

CY Wong, P Seshadri, A Scillitoe… - Journal of …, 2022 - asmedigitalcollection.asme.org
Blades manufactured through flank and point milling will likely exhibit geometric variability.
Gauging the aerodynamic repercussions of such variability, prior to manufacturing a
component, is challenging enough, let alone trying to predict what the amplified impact of
any in-service degradation will be. While rules of thumb that govern the tolerance band can
be devised based on expected boundary layer characteristics at known regions and levels
of degradation, it remains a challenge to translate these insights into quantitative bounds for …
