Automated Generation of Airfoil Performance Tables Using a Two-Dimensional Navier-Stokes Solver

摘要

A computational fluid dynamics (CFD) based methodology that greatly automates the generation of two-dimensional airfoil performance tables has been developed. The method employs a new software code, which controls a two-dimensional Reynolds-averaged Navier-Stokes flow solver. The generated data can be stored in C81 airfoil performance tables for use within comprehensive rotorcraft analysis codes. This paper reports on the development of a general automation method applied to the ARC2D flow solver, but it would be straightforward to add support for other solvers. The method is shown to perform well for its proposed purpose through the largely "hands-off" generation of C81 tables. Computations for the SC1095 airfoil section are presented and compared with experimental and existing C81 data. Time requirements for C81 table generation are also discussed.
