HYDRODYNAMIC DRAG OF 12- AND 21-PERCENT-THICK SURFACE-PIERCING STRUTS

Abstract

An investigation has been made to determine the hydrodynamic drag of three surface-piercing untapered struts at approximately 0 angle of yaw at depths up to 6 chords for speeds up to 80 fps at various angles of rake. Two struts had NACA 661-012 airfoil sections, one with a 4-inch chord and the other with an 8-inch chord. The third strut had an NACA 664-021 airfoil section and a 40inch chord.
