As part of a study of hydrodynamic impact loads on chine-immersed bodies, a model having an inverted-V transverse shape and a dead-rise angle of -20 degrees was tested at the Langley impact basin. A series of fixed-trim impacts of this inverted-V model were made in smooth water over a wide range of trim and initial flight-path angles at a beam-loading coefficient of 19.15 with a few impacts at beam-loading coefficients of 27.90 and 36.07.
