Large scale wind tunnel investigation of a semispan wing equipped with an externally-blown jet flap

M. D. Falarski, T. N. Aiken

Abstract

A wind tunnel investigation was made of the aerodynamic characteristics of a 14.5 foot semispan, externally-blown jet flap model. The model was equipped with a single 30-inch diameter, ducted fan with a 1.03 pressure ratio. The effects of flap size, fan vertical location, and wing sweep on the longitudinal aerodynamic characteristics were studied.
