Measurements of Lift Coefficients for a Family of Cones Planing on Water

Abstract

Analysis or control of the trajectory of a cavity-running projectile requires knowledge of the hydrodynamic forces acting upon the vehicle. Although it would be desirable to describe these forces and moments completely for each proposed configuration, investigation of individual body components that might be combined as a complete projectile allows prior compilation of basic data that may aid in the most favorable combination of components for a variety of applications. Insight into the nature of the basic flow problems involved and the application of model data to problems involving a full-scale vehicle, will be aided by a piecewise study of the forces acting on basic geometric shapes.
