Preliminary Design of Ground Platefor Wind Tunnel Test with CFD
Preliminary design of a ground plate, a deviceinstalled close to the aircraft model of wind tunnel test to simulate ground effect, was performed with computational fluid dynamics (CFD) techniques. Two-dimensional numerical analysis was initiated to decide the optimal leading edge and flap configurations. Then, three dimensional studies were continued to decide optimal flap deflection angle for symmetrical pressure distribution since plate and plate supporting system generate static pressure difference between upper and lower flow region. 3D simulation additionally studied the effect of the clearance between plate and wind tunnel side wall. For efficiency of computation, half model was simulated and symmetric boundary condition was applied on the center plane. Based on the preliminary design, a ground plate was designed, manufactured and tested at the Korea Aerospace Research Institute (KARI) wind tunnel. The measured pressure differences versus flap deflection angles agreed well with the predicted pressure differences.
