“…With these approaches, one can find out what is the proper approach to find a genuine aerodynamic characteristics of having 21% canard-to-wing area ratio. characteristics of KARl LSWT including static and dynamic pressure uniformity, axial pressure gradient, turbulence intensity, flow angularity, and boundary layer thickness were discussed by Arnette et aL (2000). The tests were run at the dynamic pressure of 1,500 Pa which corresponded to Reynolds number of 1.2 X 10 6 • Static force and moment data of the model configurations were measured using a pyramidal type external 6-componet strain-gauge balance.…”

A low speed wind tunnel test was conducted for a canard airplane model in KARl LSWT. The purpose of the presented paper is to investigate the proper testing approach to correct tare precisely and the interference effects for the canard models which has 21% of canard-to-wing area ratio. Most of tests were performed with image system installation for various elevator deflection conditions at the fixed canard incidence angles. To evaluate the effectiveness of the image system, the obtained correction quantity at an zero elevator setting condition with image system was applied to the rest of elevator deflections and compared with the acquired results for all elevator deflections with image system. Test result showed that the amount of correction quantities were strongly dependent on the elevator deflections, and the difference in aerodynamic coefficients for two approaches was gradually amplified as the elevator deflection angles increased. An adoption of the image system was strongly recommended for the higher canard-to -wing area ratio model, if a proper level of accuracy was required.
