Abstract

The present invention'"'"'s physical scale model (PSM) of a full-scale ship and associated degaussing system is typically embodied to include: an electrically wired, open, box-shaped framework; electronic structural modules; non-modular structural components; and, non-modular electronic components. Each edge-segment has alternating elevations and depressions for “tongue-in-groove” attachment thereto of modules and non-modular structural components, which are complimentarily raised and recessed and include selected quantities of ferromagnetic and electrically conductive material. Each module includes a ferromagnetic, electrically conductive, dimensionally scaled skin on the circuitous surface of a printed wiring board (PWB). The ferromagnetic and electrically conductive attributes of modules and non-modular structural components serve to simulate electromagnetic effects of corresponding areas (e.g., hull sections, decks, bulkheads, etc.) of the full-scale ship. The inventive PSM'"'"'s circuitry (including framework wiring, PWB wiring, and electronic components electrically connected to modules on sides opposite their skins) serves to simulate electromagnetic effects of the degaussing system.
