Abstract

A series of tests were performed in the High Speed and Free Surface Water Tunnels to measure the forces and moments on planing circular cylinders. Lift, drag, moment, and center of pressure are presented for cylinders planing on flat and laterally-curved surfaces. The ratio of the cylinder diameter to the planing surface diameter was varied from 0 to 0.538. The effects of cavitation on the forces and moments were investigated by varying the local planing body cavitation number from 0.003 to 3.3. The results of these tests show that the cavitation number cf the planing body is an important modeling parameter for cylinders. Both solid and open-ended, vented cylinders were tested.
