摘要: 传统机载导弹固体发动机弹翼/吊挂结构与燃烧室壳体的连接一般采用将弹翼/吊挂底座与壳体舱段或连接裙柱段焊接成型,吊挂/弹翼结构承载极限由焊缝强度决定;但传统成型方式已不适用于带金属吊挂结构的复合材料燃烧室壳体的成型,且轻质降本的空间有限。结合部分先进成型技术的工程化发展,针对上述问题,本文从壳体结构设计和成型方面提出了一种新型的带外挂件复合材料燃烧室壳体的一体化成型技术,并与常规带外挂件金属燃烧室壳体的设计与成型过程进行了对比分析,开展了验证复合材料壳体制备,并进行了相关承载性能及成型经济性分析,验证了该种成型技术的可行性,为后续机载/舰载导弹燃烧室复合材料壳体的成型提供了新的思路。

Abstract: The connection between the traditional airborne missile solid engine wing/suspension structure and the combustion chamber shell is generally formed by welding the wing/suspension base to the shell compartment section or connecting skirt column section, and the bearing limit of the suspension/wing structure is determined by the weld strength. However, the traditional molding method is no longer suitable for the molding of composite material combustion chamber shells with metal suspension structures, and the margin for further lightweight and cost reduction is limited. Based on the engineering development of some advanced forming technologies and in response to the above issues, this article proposes a new integrated forming technology for composite combustion chamber shells with external components from the aspects of shell structure design and forming. It compares and analyzes the design and forming process with conventional metal combustion chamber shells with external components, verifies the preparation of composite shells, and conducts relevant bearing performance and forming economy analysis, the feasibility of this molding technology has been verified, providing a new approach for the subsequent molding of composite material shells in the combustion chambers of airborne/shipborne missiles.

Key words: composite material shell with external components, integrated design and molding
