Sensitivity Analysis of the XR-3 Heave Equations to Changes in Plenum Air Leakage and Influx Rates

Abstract

A study of the CABSES vertical plane motions using the 6-DOF Program for the XR-3 craft was performed with various values of air flow rates in order to observe the sensitivity of the craft heave, e.g. acceleration and plenum pressure to variations in air flow rate. The frequency response due to regular and complex seas as well as the transient response due to a weight removal were used to observe the effect of changes in air flow rate. A linear heave-only model is shown to provide useful information concerning the effect of air flow rate on the high frequency characteristics of the XR-3 craft.
