Abstract:

A conceptual design study of a flapped, supercavitating foil has been performed in order to assess the structural feasibility of a configuration otherwise acceptable from a hydrodynamic point of view. Consideration has also been given to the design of a single, steerable strut as a supporting member for the foil. The study includes the establishment of a limit load criteria for structural design, a survey of hydrodynamic loading data for supercavitating struts and foils, calculation of design loads based upon these data for the critical loading conditions, the conceptual design of a flapped foil having a steady 1g loading of 60 tons, and a finite element stress analysis of a solid version of the foil for a more precise evaluation of leading edge and foil root bending stress than was available from simple beam calculations. A brief parametric analysis of foil bending stress trends with increased foil aspect ratio is also presented. Author
