Analysis of Test Data on the Performance Characteristics of Planing and Displacement Floats for Supporting Submerged Loads

摘要

Data on the performance characteristics of a planing float and of a displacement float, originally designed for supporting a catenary loop of minesweeping cable, are analyzed. The planing float was a prototype of the TMB planing float and was constructed of welded steel. The displacement float was in the form of a body of revolution and was constructed of balsa wood. The data on the planing float in the planing regime are compiled into a single nondimensional relationship between drag, total load, and speedlength ratio. The characteristics of the balsa-wood displacement float are also presented in nondimensional form as a family of curves of drag coefficient plotted on speed-length ratio with a load coefficient as parameter.
