In this study, we analyzed wind torque from aerostatic force coefficients of radar structures according to the Reynolds number. The test was conducted in the KOCED Wind Tunnel Center at Chonbuk University, and the wind tunnel test model was at 1:8 scale. Wind speeds were in the range of 5-26 m/s to determine Reynolds number independence. Test results of the present radar system were not impacted by the Reynolds number. Maximum drag coefficient was 1.43 under an angle of attack of 0 degrees and angle of the vehicle was 135 degrees, while maximum positive pressure coefficient was 1.21 at the side of plane in angle of attack of 0 degrees. Maximum negative pressure coefficient was -2.06 at the corner front of the plane at an angle of attack of 90 degrees. To verify wind torque in the wind tunnel test, a drive system was designed and manufactured. A wind speed of 26 m/s, the maximum average operating wind speed condition, was applied to validate the radar was driven normally. Results of this study may be used as an evaluation method for wind speed tests of radar systems and large structures that cannot be used for wind tunnel tests.
