Advanced Hull Form Inshore Demonstrator. Model Strut and Propulsor Performance in Uniform Flow

摘要

An experimental program was conducted at the Carderock Division Naval Surface Warfare Center (NAVSURFWARCEN CARDEROCKDIV) in support of the Advanced Hull Form Inshore Demonstrator (AHFID) ship for the Electric Boat Corporation. The objective of this work was to predict the ahead performance of a ducted propulsor and support struts designed for the AHFID in uniform inflow. Numerical and graphical results are presented. No anomalous performance characteristics were revealed. The total thrust and torque of the propulsor measured in the experiments should give an accurate indication of how the full-scale unit would perform in uniform flow.
