Vertical Water Entry of Some Ogives, Cones, and Cusps

reportActive / Technical Report | Accession Number: ADA009300 | Open PDF

Abstract:

An experimental investigation of the vertical water-entry deceleration of two ogive shapes and two cusp shapes is described. For each of these four shapes, the total drag coefficient and added mass are determined as functions of penetration distance. These results, combined with previous work, provide a display of possible values for maximum water-entry drag coefficient as a function of forebody fineness ratio.
