摘　　要：为解决异形、大长径比固体推进剂装药因包覆材料的收缩温度过高导致包覆胶失活、固体推进剂软化变形,使装药遭到致命性破坏的问题,设计一种侧腔的水浴加热方式。根据温度场不均匀引起自然对流的原理形成温度差,控制高温接触时间,确保包覆装药的质量一致。对侧加热腔内流体对流加热的情况进行量纲分析及过程仿真分析,结果表明,包覆样机水浴加热的水箱内加热器布局比较合理。In order to solve the problem of fatal damage of special-shaped and large length-diameter ratio solid propellant charge caused by the inactivation of coating rubber and the softening and deformation of solid propellant due to the high shrinkage temperature of coating material,a water bath heating method with side cavity was designed.According to the principle of natural convection caused by uneven temperature field,the temperature difference is formed,the high-temperature contact time is controlled,and the quality of the coated charge is ensured to be consistent.The dimensional analysis and process simulation analysis of the fluid convection heating in the side heating cavity are carried out,and the results show that the layout of the heater in the water tank heated by the water bath of the coated prototype is reasonable.
