Modular Simulation of HEI Fragments and Blast Pressure.
Abstract
The fragmentation and blast pressure of High Explosive Incendiary projectiles are major causes of aircraft fuel fires. Because Halon 1301 is being banned from DoD use as a fire suppressant, alternative fire suppressants must be developed and tested. These new suppressants must counteract the fire directly or eliminate one or more of the factors which cause the fire. To this end, this thesis takes a detailed look at the HEI processes that lead to a fire. A comprehensive review of the current knowledge and understanding of these processes is presented. In addition, hypothesized dependencies between the various processes are stated. These hypothesized dependencies can not be proved or disproved with data at this time. Therefore, tests and test set-ups are outlined to collect the necessary data. The evidence in support of these dependencies is also presented. To aid the testing of various fire suppressant system and the hypothesized HEI explosion dependencies a simulation of the HEI explosion was developed. This simulation allows the user to simulate any configuration of the aircraft dry bay, and any attack scenario for the projectile. Using this simulation one of the hypothesized dependencies was tested and sham to be possible.
