A Generalized Approach and Interim Criteria for Computing A1/N Accelerations Using Full-Scale High-Speed Craft Trials Data

Abstract

This report presents a generalized approach and interim criteria for computing the average of the 1/nth highest accelerations when analyzing accelerometer data recorded during trials of manned and unmanned small boats and craft. The computational approach and the interim criteria are based on analysis practices that have evolved over a number of years at the Combatant Craft Division of Naval Surface Warfare Center, Carderock Division as a set of best-practices for achieving repeatability when computations are performed by different data analysts. The historical background of the computational approach is summarized, the fundamental physics of craft wave encounters and wave slam events are discussed, and interim criteria for the generalized computational approach is presented. Typical data recorded during full scale trials of a high-speed planing craft is presented to illustrate results of the generalized computational approach.
