Abstract

Abstract: To evaluate the low vulnerability of an HMX-based aluminized explosive, tests were carried out, including slow cook-off tests, fast cook-off tests, shaped charge jet impact tests, 12.7 mm bullet impact tests, 12.7 mm fragment impact tests and sympathetic detonation tests, according to MIL-STD-2105D,NATO STANAG4439 and domestic correlative standards. Then the LOVA performances of explosive were judged by analyzing the residual of samples, the damage state of projectiles and verification boards, shock wave overpressure and temperature distribution. The results show that the explosive is insensitive to external stimuli, that it can withstand high overloading and satisfy the requirements of most warheads of high performance weapons, and that the test approach is practical.

Key words: explosion mechanics, aluminized explosive, low vulnerability(LOVA), cyclotetramethylenete-tranitramine( HMX), evaluation method
