为减少固体火箭发动机燃烧室衬层制造过程中产生的气泡，对气泡的来源和形成机理进行了分析和试验，通过采取控制原材料的含水量、料浆脱气的真空度以及衬层的固化温度等技术措施，大大减少了衬层中的气泡，提高了发动机的可靠性。
In order to reduce the bubbles generated in the manufacturing process of the solid rocket engine combustor liner, the sources and formation mechanism of the bubbles were analyzed and tested. By controlling the moisture content of the raw materials, the degassing degree of the slurry and the curing temperature And other technical measures, greatly reducing the bubbles in the lining, improve the reliability of the engine.
