Nonlinear theories for the analysis of section shape are used to show the interrelationship of section lift coefficient, lift-drag ratio, section modulus, leading edge stress, and center of pressure. The special effects of free surface proximity and gravity are considered using two-dimensional nonlinear theory. The finite aspect ratio effect is investigated using a linearized lifting-surface approach. All these effects are shown to reduce the cavity length at constant cavitation number. Some recent model designs at NSRDC will be discussed.Read More
