Abstract

This paper presents the results of an experimental study of the ignition and slagging characteristics for combustion of boron-containing solid propellants with ammonium perchlorate as an oxidizer under conditions modeling the operation of the gas generator and afterburner of a rocket-ramjet engine. It is shown that the introduction of fluorine-containing additives into the propellant reduces the content and adhesion capacity of primary condensed combustion products (slags). The dependences of the ignition delay on the radiant heat flux density in the range 20–180 W/cm² are obtained for model solid propellants containing boron, carbon, boron carbide, and slag particles collected in the gas generator.

含硼固体推进剂的点火和燃烧建模

摘要

本文介绍了在模拟火箭冲压发动机的气体发生器和加力燃烧室运行的条件下，以高氯酸铵作为氧化剂的含硼固体推进剂燃烧的点火和结渣特性的实验研究结果。结果表明，在推进剂中引入含氟添加剂会降低初级冷凝燃烧产物（炉渣）的含量和粘附能力。对于气体发生器中收集的含硼、碳、碳化硼和炉渣颗粒的模型固体推进剂，获得了点火延迟对辐射热通量密度在 20-180 W/cm ²范围内的依赖性。
