K1 and K, being functions of gap/chord, stagger, aspect ratio, decalage, overhang and wing thickness. The combination of existing biplane theory and experimental data supply curves from which K1 and Ks can easily be determined for any biplane. This enables the designer to calculate with reasonable accuracy the relative loading for any condition of flight.

Report No. 46I, Interference on an Airfoil of Finite Span in an Open Rectangular Wind Tunnel, by Theodore Theodorsen, 6 pages, illustrations, 23 X 29 cms. Washington, Government Printing Office, 1933. Price five cents. The wall interference on an airfoil of finite span in an open-throat rectangular section has been treated theoretically and the result is presented in a convenient formula. Numerical results are given in tables and diagrams.

The interference of the wind-tunnel boundaries on the downwash behind an airfoil has been experimentally investigated and the results have been compared with the available theoretical results for open-throat wind tunnels. As in previous studies, the simplified theoretical treatment that assumes the
