ABSTRACT

Azidodeoxycellulose (AC) is evaluated in a closed vessel as part of a propellant formulation containing nitrocellulose (NC) and nitroglycerin (NG) as binders. It is found that the AC systematically generates greater pressure and a faster linear burning rate when compared to a formulation having a similar concentration of a mixture of cellulose and NC that is meant to replicate a comparable substitution degree. An additional finding is that a formulation containing 13%wt of AC generates higher pressure in a closed vessel than the mixture of NC and NG alone. These results are evidence that AC is an adequate solid filler for propellant formulations.

摘要

作为推进剂配方的一部分，叠氮脱氧纤维素 (AC) 在密闭容器中进行评估，该推进剂配方含有硝酸纤维素 (NC) 和硝酸甘油 (NG) 作为粘合剂。发现与具有相似浓度的纤维素和 NC 混合物的配方相比，AC 系统地产生更大的压力和更快的线性燃烧速率，旨在复制相当的取代度。另一个发现是，与单独的 NC 和 NG 混合物相比，含有 13% wt AC 的配方在密闭容器中产生更高的压力。这些结果证明 AC 是适合推进剂配方的固体填料。
