DEC07-04: Fire and Smoke Simulator Model Accredited for the CVN 21 Program By Program Executive Office for Aircraft Carriers, Public Affairs
WASHINGTON -- The Fire and Smoke Simulator Model (FSSIM) was recently accredited for use in support of the CVN 78 Class Vulnerability Assessment. This accreditation marks a significant milestone in implementing the test and evaluation strategy, by the Program Executive Office for Aircraft Carriers' CVN 21 Program Office (PMS 378), for the new class of aircraft carriers.
PMS 378 employs Modeling and Simulation (M&S) throughout the Acquisition Process to accomplish trade and performance studies, ship design and testing in a credible and confident manner.
"Modeling and Simulation is a critical part of the Navy's overall effort to reduce test and evaluation cost, said PMS 378 Assistant Program Manager for Test and Evaluation Stephen Schrobo.
FSSIM is a continuous time, physics-based simulation of the spread of fire and smoke inside of a multi-compartment geometry with complex ventilation such as exists on a naval ship. The simulation was developed both to aid engineers in analyzing the effect of fire-spreading potential regarding changes in fire protection systems, both passive and active, and compartment layout, as well as, providing data on fire-related phenomena such as: temperature; smoke; CO; O2; CO2; the activation of suppression systems; and the effectiveness of active and passive fire protection, to support vulnerability and recoverability analyses.
FSSIM will be used to analyze the effects of fire and smoke spreading potential in relationship to recoverability of the carrier from a threat weapon hit. This analysis is being conducted by Naval Surface Warfare Center (NSWC) Carderock Division as part of the Live Fire Vulnerability Assessment for the CVN 78 class of aircraft carriers.
The model was developed by Dr. Jason E Floyd of Hughes Associates, Inc.; Dr. Patricia Tatem of ITT Industries; and Dr. Frederick Williams of the Naval Research Laboratory. The accreditation process was managed by Aaron Anderson of NSWC Dahlgren Division along with Rich Hardwick from EGG, Inc. under the direction of Schrobo.
