Assuming lifting line theory, expressions for velocity induced by walls at points along span of wing are derived for symmetrical airfoils with arbitrary lift distribution; calculations extended to unsymmetrical airfoils and to airfoils placed above or below center line of tunnel. Supplement to Report AR-7. (See Engineering Index 1951 p 1299).
