Abstract
Conventional insensitive munitions testing methodologies, notably the dug-out pool filled with jet fuel, have raised significant environmental concerns due to their high carbon dioxide emissions and susceptibility to fuel wastage caused by adverse weather conditions. This capstone project addresses these challenges by developing a clean-burning fast cook-off test that maintains safety standards while minimizing environmental impact. Through extensive research, engineering analysis, and testing, a prototype utilizing propane as the fuel source was developed.
The final prototype incorporates a pipe system with strategically drilled holes for propane dispersion, complemented by a triangular metal structure positioned above the system. This metal structure, featuring a vent at its apex, induces a venturi effect, optimizing airflow and promoting more complete combustion of propane. The design ensures efficient utilization of propane, enhancing combustion temperatures and test efficacy.
Extensive testing and comparative analysis were conducted to evaluate the performance of the clean-burning fast cook-off test prototype. Results demonstrated that the developed system meets or exceeds government standards for fast cook-off testing while significantly reducing environmental impact. Comparative tests against conventional jet fuel methods and alternative propane testing methodologies confirmed the superiority of the clean-burning system in achieving desired temperatures with reduced pressure requirements.
In conclusion, the capstone project successfully conceptualized, designed, and validated a sustainable solution for insensitive munitions testing. By prioritizing environmental care and innovation, the project offers a viable alternative to conventional testing methodologies, addressing environmental concerns without compromising safety or efficacy. This endeavor contributes to advancing sustainable practices within the defense industry, promoting a more environmentally conscious approach to munitions testing and evaluation.
