火箭工业正转向铝基复合材料(MMCs)主要是为减轻结构件重量，在整个发动机上大量使用铝MMCs的潜力可分为三大类：刚性从动件；中温应用和低温应用。刚性从动件包括法兰、推力室外壳、支架结构等。这些部件通过焊合和栓合连接将载荷从一个件转移到另一件上。这些部件既不与热的
The rocket industry is turning to aluminum-matrix composites (MMCs) Mainly to reduce the weight of structural parts, the potential for extensive use of aluminum MMCs throughout the engine can be divided into three broad categories: rigid follower; medium-temperature applications and low-temperature applications. Rigid follower includes flange, thrust chamber housing, support structure and so on. These parts move the load from one piece to another by welding and bolting connections. These parts are neither hot nor hot
