军事年鉴编纂刍议

编纂军事年鉴,是国务院颁布的《地方志工作条例》和全军军事志第二次工作会议赋予各大军区、省军区的任务.《地方志工作条例》明确,地方志包括志书和年鉴两个部分.全军军事志第二次工作会议提出要求,军区、省军区都要编辑军事年鉴.2010年12月,全军军事志指导小组下发的《全军军事志工作“十二五”规划》进一步指出: “各军区、省军区要继续扎实做好本级军事年鉴编纂工作的同时,适当扩大军事年鉴的编纂范围,各军区要有计划地指导所属集团军编纂军事年鉴……进一步完善我军的军事文献资料系统.     

Pressure relief of underground ammunition storage under missile accidental ignition

Safety of underground ammunition storage is an important issue, especially during the accidental ignition of missiles. This work investigates the pressure and temperature distribution of the multi-layer underground ammunition storage with a pressure relief duct during the accidental ignition process of the missile. A large-scale experiment was carried out using a multi-layered restricted space with a pressure relief duct to simulate the underground ammunition store and a solid rocket motor to simulate the accidental ignition of the missile. The results show that when the motor gas mass flow increased by 5.6 times, the maximum pressure of the ammunition storage increased by 5.87 times. At a certain motor flow rate, when the pressure relief exhaust area at the end of the relief duct was reduced by 1/2, the maximum pressure on the first layer did not change. But the rate of pressure relief was reduced and the time delayed for the pressure of ammunition store to drop to zero. In this experiment, when the motor ignition position was located in to the third layer ammunition chamber, the maximum pressure was reduced by 32.9％ and also reduced the rate of change of pressure. In addition, for the experimental conditions, the theoretical analysis of the pressure relief of the ammunition storage is given by a simplified model. Based on the findings, some suggestions to the safety protection design of ammunition store are proposed.
