摘　　要：为研究贮存条件对毛刷式装药结构火箭弹发动机固药力的影响，分别选取已在温带、热带、亚热带内陆和亚热带沿海4个地区、仓库和野外两种不同场地贮存5a的32发火箭弹发动机，首先利用拉力机对每发火箭弹发动机不同位置的8根推进剂固药力进行了测定，然后根据秩和检验方法对实验结果进行了处理与分析。通过实验与分析，得到32发火箭弹发动机的固药力，测定结果的平均值为62、11～134．79N；对于同一种贮存场地，温带与热带、热带与亚热带内陆、热带与亚热带沿海贮存地区发动机固药力之间有显著差异，其他贮存地区发动机固药力之间没有显著差异；而对于同一个地区，贮存场地对火箭发动机的固药力没有显著影响。32 Rocket motors stored in the four areas, temperate zone, tropics, inland semitropics, and coastal semitropics, and two different sites in each area, depot and field for 5 years were selected to study the influence of the storage conditions on adhesive force of rocket motor propellant charge with brush structure. The adhesive forces of 8 pieces of propellant in different position for each rocket motor were measured with the pulling force apparatus, and the experimental results were disposed and analyzed based on rank sum test method. According to experiment and analysis, the adhesive forces of propellant for 32 rocket motors were obtained. The average values of adhesive force are in the range of 62.11-134.79 N. There is remarkable influence of storage area on the adhesive force of propellant between temperate zone and tropics, tropics and inland semitropics, tropics and coastal semitropics, but there is no remarkable influence between other storage areas for the same kind of storage site. There is no remarkable influence of storage site on the adhesive forces of propellant for the same kind of storage area.
