TMB 2-, 3-, AND 4-BLADED SUPERCAVITATING PROPELLER SERIES
DAVID TAYLOR MODEL BASIN WASHINGTON DC
Pagination or Media Count:
A theoretically derived series of 2-bladed supercavitating propellers with expanded area ratios of 0.3, 0.4, and 0.5 3-bladed propellers with expanded area ratios of 0.4, 0.5, and 0.6 and 4-bladed propellers with expanded area ratios of 0.5, 0.6, and 0.7 are presented. These propellers have a specified radial distribution of the section chord and a hub radius of 0.2 of the propeller radius. The series dataARE PLOTTED IN THE FORM OF NONDIMENSIONAL COEFFICIENTS SO THAT THE PERFORMANCE OF THE PROPELLERS CAN BE EASILY PREDICTED AND A COMPLETE DESIGN OBTAINED IF DESIRED.
