Calculation of the Effect of a Supporting Strut and the Free Surface on the Drag on a Torpedo Model.

Abstract

Potential flow calculations were made to determine the effects of a supporting strut and the free surface on the drag on a test model of a torpedo. These calculations show that the strut and free surface had significant effects on the test measurements. These calculations also show that the XYZ Free Surface Program can provide useful results for Froude numbers up to but not much larger than 1.5. (Author)
