一、综述Drakkar(或L140)和 L33是围绕维金发动机设计出来的。维金发动机采用自燃推进剂四氧化二氮(N_2O_4)和偏二甲肼(UDMH),用水使燃气发生器燃气降温。操纵依靠电动液压伺服马达。第一级的四台发动机安装在构成发动机架的直径3.8米的圆筒形结构的周边。机架将推力传递到结构的其余部分。推进装置的主要组件安装在机架上面。在设想互相独立的两个推进剂贮箱应该是同样的前提下,选取了混合比。两个贮箱(用15
I. Overview Drakkar (or L140) and L33 are designed around the Veken engine. Weijin engine using self-propellant nitrogen oxide (N_2O_4) and UDMH (UDMH), water to gas generator gas cooling. Manipulation rely on electro-hydraulic servo motor. Four engines of the first stage are mounted on the periphery of a 3.8 m diameter cylindrical structure that forms the engine frame. The rack transmits thrust to the rest of the structure. The main components of the propulsion unit are mounted on the frame. The mixing ratio was chosen on the assumption that two propellant tanks independent of each other should be the same. Two tanks (with 15
