Abstract:

Experimental results are presented for various towed struts of TMB-EPH cross section and thickness ratio of 25 percent. Force coefficients, strut accelerations, and cavitation characteristics as functions of velocity and angle of attack are given for a fixed strut of strong construction and a pinned rotating strut of weaker construction. The dynamics are given for rotating struts with axes of rotation at 18 percent chord with and without a splitter plate on the trailing edge. Test results obtained in fresh water at a depth of 1 ft are used to predict the behavior of the struts in sea water at a depth of 15 ft. Author
