| 摘 要： | 为探讨燃烧产物热量对声辐射特性的影响,采用水声测试系统,实验研究了高热剂含量不同的药剂水下燃烧时的声辐射特性。结果表明,添加适量的高热剂时,能够显著提高声能。当高热剂的含量为25%左右时效果较佳,15g药剂水下燃烧时的声压级达到了158.8dB,频率主要分布在5kHz以下,但当超过25%时声能开始下降。 |

| Abstract: | In order to discuss the effect of combustion heat of the products on acoustic radiation characteristics, the underwater combustion for different thermite contents of pyrotechnic compositions were studied with underwater acoustics system. Results show that acoustic energy can be increased significantly by adding the proper content of the thermite, and the optimal thermite content is 25%. Fifteen gram pyrotechnic composition with thermite content of 25% can produce the sound pressure level as high as 158.8 dB, and the acoustic frequency is mainly 0~5 kHz,then the acoustic energy decreases with the increasing of thermite content. |
| Keywords: | military chemistry and pyrotechnic technology thermite pyrotechnic composition underwater combustion |
