THE HYDRODYNAMIC DESIGN OF FLOAT SUPPORTED AIRCRAFT. I. FLOAT HYDRODYNAMICS.

Abstract

Past research on the hydrodynamics of oscillating plates and cylinders is reviewed, and the current state of information applicable to the design of float-supported aircraft (or other vehicles) is discussed. New data are then presented, evaluated, and analyzed in light of these previous experimental and theoretical findings. These new data consist of the measured damping and added mass coefficients for circular, elliptical, and elongated cylinders, with rectangular damping plates attached at their bases. Coefficients are presented for the above configurations oscillating vertically and laterally in calm water, and held stationary in passing waves. The range of float immersion depths and oscillation amplitudes examined corresponds to that experienced by a typical float-supported aircraft in a seaway. (Author)
