As part of previous contracts, Martec Limited developed a static magnetic model of CFAV Quest for FLUX3D using an existing structural finite-element model of CFAV Quest. The model accounts for both the structural and some of the non-structural components of the ship. This report describes the work by Martec Limited for the current project in which previously developed models were used to further study the electromagnetic signature of CFAV Quest. A total of sixteen analyses were performed. Analyses included four ship headings (0° true, 90° true, 180° true and 270° true), two ship configurations (induced magnetization only, permanent magnetization only), and two aircraft altitudes (80 metres and 150 metres). The induced magnetic state of the ship was simulated by using values of zero for the permanent magnetic properties of the ship. In a similar manner, the permanent magnetic state of the ship was simulated by setting the permeability values for the ship to unity. These models were analyzed using FLUX3D and magnetic flux densities at the desired altitudes were recorded. Since the intent was to compare against field measurements, in the current study all components of the earth’s magnetic field were considered.
