The Effect of End Plates, End Struts, and Depth of Submergence on the Characteristics of a Hydrofoil

Résumé du livre

An investigation was made in Langley tank no. 2 of the effect of end plates and end-mounted struts on the lift-drag ratios of a hydrofoil. The hydrofoil had an aspect ratio of 4. The tests were made at various depths below the water surface at speeds from 15 to 35 feet per second depths corresponding to Reynolds numbers from 873,000 to 2,040,000. These speeds were all above the limiting speed of wave propagation (13.9 fps) for the 6-foot water depth used and below the range at which cavitation occurs.
