Using Field single ignition experiments of the four unconfined volume dispersion and small dosage solid FAE and TNT bombs experiments, we got the peak overpressures of solid FAE at different distances. Compared with TNT, The overpressure of FAE is 1.14~1.6 times higher than that of the TNT. Based on the theory of the air shock wave overpressure, the FAE relativity TNT mass is evaluated. At the edge of the explosive field, the number is 3.88. Pictures of high speed photography indicate that the duration and the most effect area of the FAE and TNT. Compared with TNT, obviously the FAE has more advantages. And, based on the theory of the critical concentration of dust explosion, the radius of dust explosive zone is evaluated. The phenomenon that the overpressure decays rapidly with distance is analyzed. It is suggested that the explosive temperature should be increased as the main approach to improve the FAE explosive capability in the condition when the over pressure is invariable.

通过四组无约束固态燃料空气炸药装置与等质量的TNT在野外开放空间的一次起爆对比实验，测得了不同配方组份FAE装置在不同距离的爆炸超压分布，FAE装置峰值超压比相同距离的TNT高1.14-1.6倍；并运用空气冲击波峰值超压公式计算出了FAE的等效爆炸TNT当量随距离的变化关系，在爆炸场边缘区，FAE装置爆炸当量达到了3.88倍TNT当量；通过高速摄影的图片得到了爆炸产生火球的持续时间和最大作用范围，与等质量TNT爆炸火球相比，FAE的优势明显；运用粉尘爆炸下极限浓度估算了云雾爆轰区半径，并分析了测量到的固态FAE爆炸场的压力分布单调衰减的原因；建议在保持超压不变的情况下，把提高爆温作为提高FAE爆炸性能的主要途径。
