Abstract
The Internal Ship Conflagration Control (ISCC) program was initiated to address issues raised by the missile-induced fire on the USS Stark. The overall objectives of the program were to develop guidance to the Fleet on the control of vertical fire spread and develop concepts and criteria for new ship designs. There were a number of aspects to the project. Preliminary testing at the Naval Research Laboratory (NRL) Chesapeake Beach Detachment (CBD) was performed to "design" a test fire. This test fire was intended to simulate the post-flashover fire conditions in a shipboard compartment. Concurrently, experiments were being conducted on the characteristics of propellant burning. Efforts were also initiated to characterize fire spread from a missile-induced event through computer modeling. Preliminary testing at NRL CBD also provided initial estimates of the effects of cooling and venting. This report describes the initial series of ISCC tests conducted on the ex-USS Shadwell, designated the Fire Dynamics Test Series. This series was the continuation of the CBD small-scale studies that initially characterized shipboard fire spread from a post-flashover fire. This report covers the initial heptane burns conducted in the test compartment (designated "Hep") and the Fire Dynamics diesel fuel series (designated "Die"). Where appropriate for analysis, results from subsequent Shadwell ISCC test series, including cooling ("Col") and insulation ("Ins") have been included. The objectives of the Fire Dynamics Test Series were to adapt the design fire developed at CBD to the ex-USS Shadwell test compartments and to characterize the fire spread of a post-flashover fire on a large scale. The design fire was also to serve as the basis for future insulation, venting, cooling, and manned intervention tests. This report provides the baseline documentation of the test spaces and the fundamental heat transfer data.
