Manufacturing of Stress Physical Scale Models (SPSMs) for Signature Reduction and Resistance to Environmental Stress

The use of stress physical scale models allows the Navy to design ship magnetic field signature reduction systems into Navy vessels. Current methods for fabricating the stress physical scale models (SPSM) are expensive and are not timely enough to allow introduction of the signature reduction system into the ship build early in the cycle.

TRI Austin investigated SPSM fabrication processes that can allow rapid turnaround between ship drawings and completed SPSM. These methods can be less expensive than legacy SPSM fabrication processes.
