Report No. ARL-TN-179
Authors: William A. Spurgeon and Charles Beauchamp
Date/Pages: June 2001; 34 pages
Abstract: This technical note describes the fabrication of a composite airfoil shaped part that could twist easily about its long axis, but would not flex easily. This part was fabricated using a polyurethane resin matrix glass reinforced composite material that performed satisfactorily in wind tunnel tests. Possibilities for scale-up to very large parts are described.
