Abstract:

A reassessment of overall technical performance parameters of naval vehicles leads to the definition of specific energy as a measure of vehicle efficiency. Specific energy is an energy efficiency equal to the product of transport efficiency and Froude number. In terms of specific energy, the empirical performance data for fluidborne vehicles converge to yield systematic trends with Froude number for fully-immersed buoyant vehicles, surface ships, and dynamic-lift vehicles. Specific energy appears to be a new consistent basis for comparing the overall technical efficiency of past, present and future naval vehicles. Author
