Abstract
Smoke control tests were conducted onboard the ex-U.S.S. Shadwell from August 26 through September 5, 1991 to evaluate the performance of the most recent Arleigh Burke (DDG 51) class flight 2 smoke control system design and to develop baseline design criteria and performance data. The capability of the system to desmoke a damage control (DC) deck and to limit smoke propagation under varying fire sizes and ventilation conditions was evaluated. The tests were designed to determine the performance of a smoke control system design for a DC deck. The DC deck system uses increased ventilation rates to enhance desmoking and to limit smoke propagation. The results of these tests characterized the performance of the system under smoke conditions produced by a fire in a machinery space located below the DC deck but with access to the DC deck. A series of tests on the performance of balanced self-closing (Ellison) doors in the area from the machinery space to the DC deck were also conducted. Results indicated that the smoke control systems design provided significant improvement in desmoking capability, as well as limiting smoke movement with the access doors unsecured. The Ellison door tests demonstrated that a properly installed aluminum door provides a substantial barrier to the spread of smoke and fire under moderate thermal exposure conditions.
