Abstract

Team 11 was presented with a task from Naval Ordnance Safety and Security to develop and design a method of creating a clean burning system to cook off military munitions. Specifications that were presented to the team included: The apparatus must be a certain size to encapsulate flames around all to be tested munitions. The design must reach a desired temperature in a finite time, as well as hold a consistent higher temperature for the duration of the test. The burner also had to be modular, meaning it could be taken apart to be stored while not in use, and easily assembled when needed. Finding a solution to line freezing was another design specification, liquid propane converting to vapor propane draws heat from the ambient air causing piping and components to become cold. The temperature combined with ambient humidity causes freezing. Solutions to these specifications were initially outlined and generated by each team member. The best solutions to each specification were then cross referenced to ensure there were no patent infringements on pre-existing designs. A QFD analysis was then performed to vet out the best designs generated.

With understanding how to meet these specifications, a design had to be generated. The team used resources of a pre-existing system to assist with modeling the design. Key aspects such as fuel type and required pressure to achieve the specifications were taken from the already existing system. Having complete knowledge of the design, the team was then able to begin simulating to assure the initial build would meet the requirements needed. Simulations for fluid flows, burn rates and temperatures were conducted successfully and proved that the design would meet the requirements.

With the knowledge and data in hand, the team was able to begin the initial build. Limited funding created a slight hurdle for the team in the beginning, but with a few generous donations of material, and labor, an initial design to test was created. After testing, the initial design did not perform as the simulations predicted. Adjustments were made and retesting of the final design took place, giving better results but still not meeting some of the requirements. A plan of action for future teams tasked with this project was then created to streamline already completed work.
