摘    要:某固体火箭发动机燃烧室为锥筒室,内绝热层很薄,包括复合绝热层和橡胶绝热层两层,由于燃烧室几何形状特殊,无法采用现有的内绝热层成型工艺技术,在分析基础上,得出了该内绝热层压制精密控制方法,利用定位和壳体保护装置,将配制的未硫化粘稠态橡胶通过压涂覆在壳体内壁,精确控制内绝热层的厚度和均匀性,该发动机热试车成功表明,这种内绝热层成工艺技术是有效可行的。

关 键 词:成型工艺  固体推进剂火箭发动机  内绝热层  精密控制

Forming process improvement of an internal insulation with cone
Abstract:A solid rocket motor has a cone cylinder combustion chamber and its insulation is a double layer structure, which consists of composite insulation and rubber insulation Because of the special geometry of the chamber, it is difficult to use the forming process of insulation in common use A precisely controlled processing method of the internal insulation of the chamber by using a locating and case protection device was developed In accordance with the method, high viscosity un vulcanized rubber was coated on the inner wall of case and the thickness and uniformity of the rubber layer were accurately controlled The motor firing tests shows that the forming process of internal insulation is feasible and effective
Keywords:solid propellant rocket engine  internal insulation  precise control  positioning
