本文叙述了对战术导弹的要求及实现二级推力程序可能的动力装置方案,并对这些方案进行了比较.提出了一、二级推力比和总冲比是选择动力装置方案的重要参数.当推力比大于5时,不宜采用单室双推力方案,尤其是在一、二级推力比较大而总冲比较小的情况下,选用贯穿式双室双推力方案较有利.文中进行了实例对比.当一、二级推力比很大,而总冲比又很小时,采用组合式固体火箭冲压发动机是一种很可取的方案.本文还概述了无喷管固体火箭发动机在组合式固体火箭冲压发动机及其它二级推力动力装置上的应用.
This paper describes the requirements for tactical missiles and possible power plant solutions for implementing the second-stage thrust program, and compares these solutions. The primary and secondary thrust ratios and the total red ratio are important parameters for selecting a power plant solution. Thrust ratio greater than 5, should not be used single-chamber double-thrust scheme, especially in the first and second thrust relatively large and relatively small total case, the choice of through double chamber double thrust scheme is more favorable. When the ratio of primary and secondary thrust is large and the total ratio is very small, it is a preferable solution to adopt the combined solid rocket ramjet.The paper also summarizes the advantages of the nozzleless solid rocket motor in the combined solid rocket ramjet And other second-tier thrust power plant applications.
