Blade Envelopes Part II: Multiple Objectives and Inverse Design

Abstract Blade envelopes offer a set of data-driven tolerance guidelines for manufactured components based on aerodynamic analysis. In Part I this two-part paper, workflow the formulation blade is described and demonstrated. II, extended to accommodate multiple objectives. This allows engineers prescribe manufacturing that take into account performance criteria. The quality can be correlated with features derived from distribution primal flow quantities over surface. We show these distributions accounted in envelope using vector-valued models discrete surface measurements. Our methods result variables flexible independent control characteristics metrics, similar spirit inverse design methods. augmentations presented paper are demonstrated LS89 turbine blade, focusing loss, mass flow, isentropic Mach number distribution. Finally, we demonstrate how used visualize invariant designs by producing 3D render modeling software.
