Results of rolling moment measurements on wing-body models in closed and ventilated test sections have been presented. The tests have been conducted in the NAL 1.2, and 0.3m wind tunnels. Systematic rolling moment variations with roll angle have been observed when the test section wall open area ratios are different for top (or buttom) and sidewalls. The magnitude of the wall induced rolling moment is found to decrease with Mach number in the test range M = 0.5 to 1.2.
