Transcription

1 Static Detonation Chamber M67 Rocket Motor Testing May 2016 Presented to: The 19 th Annual International Chemical Weapons Demilitarisation Conference Presented by: Tim Garrett Anniston Site Project Manager APPROVED FOR PUBLIC RELEASE DISTRIBUTION UNLIMITED

2 Objective Determine Viability of Processing M67 Rocket Motors (RMs) in the Anniston Static Detonation Chamber (SDC) Support Permitting Actions to Increase Net Explosive Weight Limits: Resource Conservation and Recovery Act/Department of Defense Explosives Safety Board Collect SDC Emissions Data From M67 RM Testing 2

3 M67 Rocket Motor 3

4 Current Regulation Status Resource Conservation and Recovery Act Permit Limit <6.7 Pounds of Net Explosive Weight (NEW) Per Feed Department of Defense Explosives Safety Board <5.29 Pounds NEW Per Feed for Class 1.1 Explosives Dynasafe s Position - The Static Detonation Chamber is Capable of Safely Processing Higher NEW for Propellant 4

5 Modeling First Model M8 Propellant Second Model M67 Rocket Motors (RMs) (M28 Propellant) Used a Conservative Value to Predict Rupture Pressure of RM Casing (10 MegaPascal (MPa)) Concern About Overheating with Repeated Feed Added Atomizing Water Spray 5

6 Recommended Test Criteria Model Based Detonation Chamber 260 Pounds Per Square Inch Gauge (psig) Buffer Tank 87 psig Loading Chamber psig 6

7 Study 3 Phases Phase 1 Process D541 M1 Propellant Gradually Increasing Net Explosive Weight (NEW) up to Approximately 23 Pounds 80% of 23 Pounds > NEW of an M67 Rocket Motor (RM) (18.13 Pounds NEW) Ramp-up Began 27 Aug 15 Approximate 1 Pound Increments from 7.30 Pounds to Pounds Maximum Feed Events of Pounds Conducted on 22 and 23 Oct 15 Process M28 Propellant Grains from an M67 RM at Approximately 23 Pounds Completed on 7 Jan 16 Feeds of 8.96 Pounds, Pounds, and Pounds Pressures Within Recommended Values 7
