Abstract
The effort discussed in this report was an investigation into advanced ullage protection methods for an aircraft fuel tank. The approach used was to first review the raw test data of three separate fire/explosion suppressant test programs to determine their relation to each other and their applicability to the overall effort. Second, based on the data review, determine the performance of each agent used in the tests, the concentration levels used and whether the test setup and conduct of each separate test influenced the results. Third, to identify any data trends and/or data voids that could possibly be clarified with additional testing, and fourth, to document the results of the overall effort. The test programs reviewed and discussed in this report are the results of gun-fire tests conducted intermittently over a seven-year span at the Aircraft Survivability Research Facility (ASRF), Wright-Patterson Air Force Base, Ohio and are presented in three phases. The objective of Phase A was to investigate the effects of venting, threat type, striker plate material and tank wall simulator (TWS) size on the effectiveness of Halon 1301 and nitrogen inerting. The objective of Phase B was to test the inerting effectiveness of Halon 1301 against 0.50 cal. API and 23-mm HEI projectiles under the conditions of higher temperatures and pressures anticipated in the F-16 fuel tank. The objective of Phgase C was to expand the Phase A work on venting with a broader range of conditions, including nitrogen and halon inerting and 23-mm and 30-mm HEI projectiles.
