Study on Manufacturing Tolerances for the Laminar Airfoil

The procedure to determine manufacturing tolerances for the laminar airfoil is explained using the CFD (computational fluid dynamics) analysis. This procedure is applied to a laminar airfoil for the tolerance of the forward-facing step and rearward-facing step. In the CFD analysis the Langtry-Menter SST Transition model is used to simulate a natural transition over the laminar airfoil. The computed tolerances showed good agreement with experimental data.Copyright © 2015 by KSME
