ANALYSIS OF A SUB-DETONATIVE MUNITION RESPONSE FRAGMENT THROW DISTANCE

摘要：

Insensitive Munitions (IM) testing commonly produces sub-detonative munitions response. The ballistics community needs to be aware that fragment throw distances can be much further than is predicted using established Hazard Fragment Distance (HFD) analysis due to sub-detonative munition response. A test was conducted using an unfuzed M107 155mm artillery projectile, where the projectile was purposely subjected to non-standard initiation using a shaped charge. Through collected data and technical analysis, it was concluded that the M107 projectile did not fully detonate high order, but rather produced a sub-detonative response. The test generated a 0.84 kg (11b 14 oz.) steel fragment that traveled 1824 m (5984 ft.), thereby greatly exceeding the established HFD. Through technical analysis, it was determined that the proximal root cause of the failure was the unexpected low aerodynamic drag flight of the fragment. Low drag flight probably resulted from a combination of occurrences including non-standard initiation, sub-detonative response of the explosive and subsequent generation of a large flat fragment that was gyroscopically stabilized to travel in a nearly edge-on orientation.
