18.1 燃烧室尽管液体火箭发动机的结构各异,但其主要组成部分和制造要求却有许多相同之处。现在,以美国的“西格玛”和苏联РД-107为例,研究一下液体火箭发动机组合件装配和总装配的工艺特点。液体火箭发动机燃烧室(图18.1)由头部А、燃烧室Б和喷管В三个主要部分组成。燃 18.1 Combustion Chamber Although liquid rocket motors have different configurations, the main components and manufacturing requirements have much in common. Now, take the example of the “Sigma” in the United States and the Soviet model “РД-107” as an example to examine the process characteristics of assembly and assembly of liquid rocket engine assemblies. Liquid rocket engine combustion chamber (Figure 18.1) by the head А, the combustion chamber Б and the nozzle В three main components. Burning
