【摘要】 采用解析计算法,计算了NEPE高能复合固体推进剂的爆速和爆压。通过对冲击波超压进行计算,确定了超压与距离的关系,并与试验结果进行了对比。通过研究冲击波在空气中的衰减情况,确定出推进剂爆炸后的安全范围。研究结果表明,在无掩蔽的情况下,高能固体火箭发动机爆炸冲击波超压对人员有杀伤作用的距离为82 m,爆炸后人员的安全距离为120 m。更多还原

【Abstract】 Explosion velocity and pressure of NEPE high energy solid propellant were calculated by means of analytic calculation methods.The relationship of overpressure and distance was determined through overpressure calculation of explosion wave,and the calculation results were compared with experimental results.The safety distance for propellant explosion was determined by the study on the attenuation of blast impact wave in the air.The investigation results show that the damage distance of explosion wave overpressure to human is about 82 m under the situation of no shelter,and the safe distance to human is about 120 m for explosion.更多还原
