There is concern over the applicability of current aircraft rescue firefighting ARFF protection standards for New Large Aircraft NLA such as the Airbus A380 and Boeing 777. Current protocol is based on traditional aircraft in comparison NLA are characterized by unusually large dimensions, composite material integration, as well as enhanced passenger and wing loading, and stored fuel in non-conventional locations. A study is underway to develop an aircraft-crash-fuel spill-fire-suppression ACFFS simulation framework to quantify fuel dispersal and to estimate firefighting agent application requirements for accidental scenarios of high interest. The current work presents the design, development, and results to date of sub-scale NLA pool fire-suppression simulations and supporting experiments conducted at the Indoor Fire Testing Facility at Tyndall AFB, FL. Suppression experiments were conducted on a 110-scale partial NLA steel mockup designed to resemble major mid-body features of the Airbus A380 engulfed in a 3-m diameter JP-8 pool fire. Computational fluid dynamic CFD model development is currently in progress.
