Investigation of the Effect of the Fuselage on the Wing of a Low-Wing Monoplane (open access)

Investigation of the Effect of the Fuselage on the Wing of a Low-Wing Monoplane

Memorandum presenting the mutual action of wing and fuselage, which greatly affects the construction of airplanes. A description of systematic wind-tunnel tests that were made to answer that question is provided. Other tests deal with the transition from fuselage to wing root, which, if inadequate on low-wing monoplanes, may become dangerous by causing the air flow to separate at the wing root.
