Evaluation of Auxiliary Agents and Systems for Aircraft Ground Fire Suppression -Phase II.

摘要

An experimental program was conducted to assess the capabilities of three extinguishing agents under similar fire test conditions. The agents tested were a carbamic powder (CP), halon 1211,and an experimental modification of potassium bicarbonate (PKX). Tests were first conducted to select appropriate nozzles and operating pressures for PKX portable and wheeled extinguishers and halon 1211portable units. The operating characteristics of portable and wheeled units for all three agents tested are provided. Fire extinguishing tests were next conducted on reproducible configurations simulating interior and exterior aircraft fire conditions. Interior fires included electrical fires,compartment fires involving various individual and mixed fuels and hidden oil fires. Exterior fires included those occurring in helicopter engine stacks,engine nacelles,the reticulated foam of some aircraft tanks,and those involving fuel burning on aircraft wings and cascading fuel fires.
