箱式垂直发射系统燃气流的排导

Exhaust of Combustible Airflow of Box-Shaped Structure Vertical Launch System

阐述了箱式垂直发射系统燃气流合理排导的必要性。在对内导流和外导流两种燃气流排导方式进行分析比较的基础上 ,指出了燃气流外排导的局限性。认为燃气流内排导由于具备结构简单、空间利用率高、通用性强、安全性高等优点 ,适合于垂直发射燃气流的合理排导 ;尤其是同心筒式发射装置燃气流的排导将成为箱式垂直发射系统燃气流排导的发展方向。

This essay explains the necessity of proper exhaust of combustible airflow, compares inner guide with outer guide. It takes USA MK-41 as an outer guide example to explain the limitations of outer guide. It introduces the merits of inner guide ——simplicity of structure, high space utilization ratio, high efficiency in common usage, high-security——fitting for proper exhaust of combustible airflow of vertical launch system. This essay especially focuses on exhaust of combustible airflow of homocentric-tube launch system which will be the development direction of combustible airflow exhaust of box-shaped structure vertical launch system.
