WebRECOMMENDATIONS Since closed bomb testing can greatly expedite the assessment of increment propellant for the 81 mm mortar, and is relatively inexpensive compared to the cost of proof firing, this method should be used together with proof firing tests until sufficient data is acquired to as- certain the validity of the equations de- rived from … WebThe testing included closed bomb combustion and dry screening of the damaged LX-10 samples and gauged the damage vulnerability of the energetic material to mechanical insult. The work was funded by the Lawrence Livermore National Laboratory. The screened size fractions of the damaged spherical LX-10 samples will be
