150403-N-PO203-108 WEST BETHESDA, Md. (Apr. 3, 2015) A ship hull model attached to a high-speed sled moves through waves at the Naval Surface Warfare Center (NSWC) Carderock's David Taylor Model Basin, in West Bethesda, Md., during Office of Naval Research (ONR)-sponsored research. The purpose of the research is to study the fundamental physics of the water-impact of high-speed planing hulls and to measure the slamming loads and resulting motions of the craft upon re-entry into the water which can cause structural damage and injury to passengers.
