Large-scale Wind-tunnel Tests of an Airplane Model with a 45 Degree Sweptback Wing of Aspect Ratio 2.8 with Area Suction Applied to Trailing-edge Flaps and with Several Wing Leading-edge Modifications

D. G. Koenig, K. Aoyagi

Abstract

Report presenting an investigation of an airplane model conducted to determine the effect of area-suction trailing-edge flaps and several leading-edge modifications on the aerodynamic characteristics of a 45 degree sweptback wing. Results regarding the effect of trailing-edge flaps on the aerodynamic characteristics of the model with horizontal tail off, effect of wing modifications on the high-lift characteristics of the model with the horizontal tail off, aerodynamic characteristics of the model with the horizontal tail installed, and area-suction requirements are provided.
