Interference of wing and fuselage from tests of 17 combinations in the NACA variable-density tunnel combination with special junctures

Sherman, Albert
March 1938

As part of the wing-fuselage interference program in progress in the NACA variable-density wind tunnel, a method of eliminating the interference bubble associated with critical mid wing combinations was investigated. The interference bubble of the critical mid wing combination was shown to respond to modification at the nose of the juncture and to be entirely suppressed with little or no adverse effect on the high-speed drag by special leading edge fillets.
