Refinements of the Seal Subroutines and Fan Air Flow Maps for the XR-3 Loads and Motion Program.

Abstract

Refinements to the bow and stern seal subroutines of the XR-3 Loads and Motion computer program are made. New lift fan performance maps are developed and presented. Comparison studies of simulated performance of the original XR-3 model with the old and new fan maps are made under varying sea conditions. Measured roll and pitch transient behavior of the XR-3 test craft in calm water is compared with the simulated response of both the original and the new model. In addition, simulated performances of the original and new models in irregular ahead seas are compared.
