EXPERIMENTAL MEASUREMENTS OF THE STEADY LIFT, DRAG, AND MOMENT ON SURFACE-PIERCING STRUTS.

Abstract

Testing of two surface-piercing strut configurations for the Pitch-Heave Oscillator is described. Experimental measurements were made of the steady lift, drag, and moment on two rectangular planform, finite aspect ratio struts at finite Frounde numbers. The first model section had identical symmetrical ogival fairings on the leading and trailing edges and a flat center section. For the second configuration the aft ogive fairing was cut off the first model section, and a square trailing edge was left. The model force and moment coefficients are presented and the wake, spray, and cavitation characteristics of both profiles are discussed. Preliminary computations of the theoretical pressure distributions for 8 two-dimensional sections and computed full-scale forces and moments for the PHO-2 strut configuration are included. (Author)
