A Model Study of Coupled Amphibious Vehicle Trains in Calm Water and Waves.

Abstract

A model investigation of the performance of trains of up to four amphibians in calm water and waves. Measurements include the inter-vehicle towing force and the unequal division of drag among vehicles in the train is demonstrated, necessitating rigid couplings between vehicles. The optimum vehicle spacing and attitude is determined. Significant improvements in speed made good are obtained, for a given amount of installed power per vehicle, by increasing the number of vehicles in the train. The value of deploying bow flags in vehicle trains is shown. Data for both 14 ton and 26 ton vehicles at speeds up to 25 mph is included. (Author)
