INTERFERENCE OF WING AND FUSELAGE FROM TESTS OF 30 COMBINATIONS WITH TRIANGULAR AND ELLIPTICAL FUSELAGES IN THE NACA VARIABLE-DENSITY TUNNEL

摘要

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 HACA 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.nThe parameters of combination for title 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 ellip¬tical cross sections.
