Interference of Tail Surfaces and Wing and Fuselage from Tests of 17 Combinations in the N.A.C.A. Variable-Density Tunnel
This is a 1939 NACA technical report by the National Advisory Committee for Aeronautics, issued as a NASA Technical Reports Server record, presenting wind-tunnel results for tail, wing and fuselage interference across 17 model combinations tested in the Variable-Density Tunnel for aeronautical engineers. Its pictures pair line graphs of lift coefficient against effective downwash and pitching moment with photographs of smooth-skinned model aircraft in front, side, and three-quarter views, showing streamlined fuselages, elliptical tail surfaces, and low wings a designer could use for sleek aircraft silhouettes.
