Finite element thermal analysis of 155-mm projectile exudtion inside a hot gun tube.

PDF Version Also Available for Download.

Description

The high firing rates of new and developing cannons create higher operating temperatures than projectiles experience. Higher temperatures in-bore bring the possibility of high explosive exudation from chambered shells during misfire, hang-fire, or hold-fire. The development of a finite element thermal model to predict high explosive exudation inside a hot gun tube brings an improved level of insight to existing physical test results. The MI98 towed howitzer and M107 155-mm shell are modeled to compare to physical test results from Morales 1997 and Zimmerman 1980. During creation of the model special focus is taken to simulate the heat flow between ... continued below

Description

The high firing rates of new and developing cannons create higher operating temperatures than projectiles experience. Higher temperatures in-bore bring the possibility of high explosive exudation from chambered shells during misfire, hang-fire, or hold-fire. The development of a finite element thermal model to predict high explosive exudation inside a hot gun tube brings an improved level of insight to existing physical test results. The MI98 towed howitzer and M107 155-mm shell are modeled to compare to physical test results from Morales 1997 and Zimmerman 1980. During creation of the model special focus is taken to simulate the heat flow between the contact of the rotating band and cannon wall. A strong correlation between test results and model is seen with both reports and validates the model setup. Model results suggest that time to exudation predicted by Morales and Zimmerman may be too conservative.
