“阿里安”L5是欧洲研制的最重要的中等推力级可贮存的二元推进剂发动机.它采用了多元件喷射器的设计原理,这种喷射器使用多个同轴喷射元件、一个燃料再生冷却燃烧室和一个辐射冷却的喷管扩展段.研制该发动机各部件所运用的技术与MBB-ERNO公司研制“阿里安”HM7液氧/液氢发动机时运用的技术相类似,但由于L5发动机的推进剂具有二元的基本特性,故现有的液氧/液氢技术只能部分采纳.对此MBB-ERNO公司提出了一项实验性计划来论证同轴式喷射器原理的可行性.L5发动机的研制工作包括整台发动机的设计及推进分系统的布局.叙述L5发动机的设计、性能和工作特性,以及研制状况,重点介绍目前正在研制的喷射器.
The “Allianz” L5 is the most important mid-lift, storable, binary propulsion engine developed in Europe that uses the design principle of a multi-element injector that uses multiple in-line injection elements, a fuel regeneration Cooling the combustion chamber and a radiant-cooled nozzle extension.The technology used to develop the various components of the engine is similar to that used by MBB-ERNO in the development of the “Allianz” HM7 liquid oxygen / liquid hydrogen engine. However, due to the L5 engine Of the propellant has the basic characteristics of the binary, so the existing liquid oxygen / liquid hydrogen technology can only be partially adopted.To this MBB-ERNO company proposed an experimental plan to demonstrate the feasibility of coaxial injector principle. L5 engine development work includes the design of the entire engine and the layout of the propulsion subsystem.Describes the L5 engine design, performance and operating characteristics, as well as the development of the situation, focusing on the currently under development of the injector.
