Tests of 12 wing-fuselage combinations employing triangular and 18 employing elliptical fuselages were made in the NACA variable-density tunnel as a part of a program to investigate at large values of Reynolds number the aerodynamic effects of wing-fuselage interference. This program is outlined in NACA Report No. 540, which contains the test results for 209 combinations, 202 with round and 7 with rectangular fuselages, comprising the basic part of the wing-fuselage interference investigation. The parameters of combination for the triangular and elliptical fuselages covered in the investigation were vertical position of the wing with respect to the fuselage axis wing shape and wing-fuselage juncture shape. The results bear out the general conclusions advanced in the discussion in NACA Report No. 540 and provide data concerning the wing-fuselage interference of fuselages of triangular and elliptical cross sections.
