Abstract
Since the ban on the production of Halon chemicals in the early 1990’s, new methods for controlling fires, especially within engine nacelles and dry bays, are constantly being sought. A unique facility is described that emulates the flow field between a gas turbine engine and a nacelle. Results are provided of the effects of delivering a Halon replacement chemical within a simulated engine nacelle. Simulated live firing within the facility provides for the evaluation of a solid propellant gas generator (SPGG), with the validation of the SPGG being dependent on its ability to suppress a JP-8 fuel fire. This paper will discuss and present data concerning the flow visualization within the newly designed engine/nacelle simulator, the velocity fields, as well as the ability of a SPGG to suppress a fire produced at different locations within the test article.
