Abstract:

Experimental results obtained at high Froude number for a series of NACA 4 digit airfoil section surface-piercing struts show that the spray drag is essentially independent of operating Froude number and strut leading edge radius. The spray drag increases with strut thickness ratio and can be as much as 40 of the strut profile drag for typical operating conditions.
