EXPERIMENTAL INVESTIGATION OF THE VENTILATION OF VERTICAL SURFACE-PIERCING STRUTS IN THE PRESENCE OF CAVITATION

An experimental program was conducted in the Lockheed underwater missile facility to determine the mechanism, characteristics, and the significant parameters controlling ventilation in the presence of cavitation for three streamlined, vertically, surface-piercing strut models. Tests were performed for speeds from 20 to 30 fps, for yaw angles from 6 to 10 degrees, for submergences of 1 to 1.5 chord lengths. The radius of the leading edge of the struts ranged from 0 to 0.0327 chord lengths. Forces were measured and flow photographs were obtained. The importance of vapor cavitation number as the principal parameter influencing the inception of ventilation was demonstrated.
