Interference of Wing and Fuselage from Tests of 28 Combinations in the NACA Variable-Density Tunnel
This NACA technical report from 1937, issued by the National Advisory Committee for Aeronautics, presents wind-tunnel test results for wing and fuselage combinations in its Variable-Density Tunnel, written for aeronautical engineers. Its plotted graphs of drag and pitching-moment coefficients against lift coefficient, with small plan-view sketches of each wing-body arrangement, show how fillets and engine cowlings change performance, a layout a designer could borrow for clean technical charts with labelled curves.
