Lift and drag measurements were obtained on a semispan circular cylinder having a lengthdiameter ratio of 4 (aspect ratio 8) and an end plate of 2.5 diameters. The investigation was made to determine to what extent the characteristics are affected by groundboard height. Tests were made over a momentum coefficient range from 0.14 to 4.6 and groundboard height ranging from 1.5 to 10 diameters from the cylin er axis. The test Reynolds number was approximately 290,000.
