Detonation velocity as a function of charge diameter is reported for Alliant Bullseye powder. Results are compared to those of mixtures of ammonium nitrate mixed with aluminum and ammonium nitrate mixed with fuel oil. Additionally, measurements of free surface velocity of flyers in contact with detonating Bullseye are presented and results are compared to those of hydrocode calculations using a Jones–Wilkins–Lee equation of state generated in a thermochemical code. Comparison to the experimental results shows that both the free surface and terminal velocities were under-predicted.

Bullseye 粉中的直径效应

报告了 Alliant Bullseye 火药的爆炸速度与装药直径的函数关系。结果与硝酸铵与铝混合的混合物和硝酸铵与燃料油混合的结果进行比较。此外,还提供了与引爆靶心接触的传单的自由表面速度的测量值,并将结果与​​使用热化学代码中生成的 Jones-Wilkins-Lee 状态方程的水代码计算的结果进行比较。与实验结果的比较表明,自由表面和终端速度都被低估了。
