Lift and pitching-moment interference between a pointed cylindrical body and triangular wings of various aspect ratios at Mach numbers of 1.50 and 2.02 / Jack N. Nielsen, Elliott D. Katzen, and Kenneth K. Tang.
In order to investigate the effects of interference on wing-body combinations, tests were conducted at Mach nuaibersof 1.50 and 2.02 of a pointed, cylindrical body, of six triangular wings having asyect ratios from 0.67 to 4.00, and of the whgs and the body in combination. The body had a fineness ra...

| Summary: | In order to investigate the effects of interference on wing-body combinations, tests were conducted at Mach nuaibersof 1.50 and 2.02 of a pointed, cylindrical body, of six triangular wings having asyect ratios from 0.67 to 4.00, and of the whgs and the body in combination. The body had a fineness ratio of 7.33, a conical nose with a semiapex angle of 15 degrees, and an ogival trsmsition section to a cylindrical afterbody. The wings had 8-percent-thick double-wedge sections with the maximum thickness at the midchord, and the wing-body combinations were made by inserting the wings at zero incidence into the cylindrical pait of the body. Experimental lift and pitching-moment results were obtained for a nominal angle-of-attack range of plus or minus 5.5 degrees and a constant Reynolds number, based on the body length, of 5.5 million. Theoretical characteristics of the body and wings alone and in combination, as well as the interference, were calculated from the available theories and compared with the experimental results. |
