Gas Transport in the Insensitive High Explosive PBX 9502

摘要

Abstract >Small‐scale laboratory experiments were performed to analyze gas transport mechanics in PBX 9502, an insensitive high explosive (IHE) composition. Two independent investigations are reported here. First, gas permeametry and dynamic pycnometry techniques were used to measure the molecular flow (Knudsen) coefficient and the internally interconnected void fraction of pristine and thermally damaged samples in two uniaxial pressing orientations. The permeability of PBX 9502 was found to be unmeasurably low (of the same order of magnitude as PTFE) with gas transport being diffusion‐dominated. Secondly, a pressure vessel experiment was developed to measure quasi‐static and dynamic gas generation as the explosive was heated to self‐ignition (cookoff). The gas generation results and the permeability/diffusivity findings provide evidence that PBX 9502 remains impermeable until seconds prior to self‐ignition. At ignition, internal void‐pressure drives macro‐scale cracking and the sample becomes uniformly incorporated in the following deconsolidating deflagration. These results are discussed within the context of previous observations of pressure‐dependent cookoff behavior of PBX 9502 and provide a more complete description of thermal damage evolution in this explosive composition. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >进行小规模实验室实验，以分析PBX 9502中的气体输送力学，不敏感的高爆炸（IHE）组合物。这里报告了两个独立的调查。首先，使用气体偏心和动态脓性技术来测量分子流量（knudsen）系数和在两个单轴按取向中的原始和热损坏样品的内部互连的空隙部分。发现PBX 9502的渗透性是不可估量的低（与PTFE相同的数量级），具有扩散主导的气体传输。其次，开发了一种压力容器实验，以测量准静态和动态气体产生，因为炸药被加热到自燃（烹饪）。气体产生结果和渗透/扩散结果提供了证据，即PBX 9502在自点火之前的速度仍然是不可渗透的。在点火时，内部空隙压力驱动宏观裂纹和样品在以下脱屑液相中均匀地掺入。这些结果在PBX 9502的依赖性克服行为的先前观察的背景下讨论，并在该爆炸性组合物中提供了热损伤演化的更完整描述。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-29946/'>《Propellants, Explosives, Pyrotechnics》</a> <b style="margin: 0 2px;">|</b><span>2020年第6期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Englert‐Erickson Michael A.&option=202" target="_blank" rel="nofollow">Englert‐Erickson Michael A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Holmes Matthew D.&option=202" target="_blank" rel="nofollow">Holmes Matthew D.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Parker Gary R.&option=202" target="_blank" rel="nofollow">Parker Gary R.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Schmidt Chad C.&option=202" target="_blank" rel="nofollow">Schmidt Chad C.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Meyer Brad A.&option=202" target="_blank" rel="nofollow">Meyer Brad A.;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Explosive Science and Shock PhysicsLos Alamos National LaboratoryLos Alamos 87544 NM USA;</p> <p>Explosive Science and Shock PhysicsLos Alamos National LaboratoryLos Alamos 87544 NM USA;</p> <p>Explosive Science and Shock PhysicsLos Alamos National LaboratoryLos Alamos 87544 NM USA;</p> <p>Gas Transfer SystemsLos Alamos National LaboratoryLos Alamos 87544 NM USA;</p> <p>Gas Transfer SystemsLos Alamos National LaboratoryLos Alamos 87544 NM USA;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1837.html" title="爆炸物工业、火柴工业">爆炸物工业、火柴工业;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=PBX 9502&option=203" rel="nofollow">PBX 9502;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cookoff&option=203" rel="nofollow">Cookoff;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Permeability&option=203" rel="nofollow">Permeability;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Diffusivity&option=203" rel="nofollow">Diffusivity;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=TATB&option=203" rel="nofollow">TATB;</a> </p> <div class="translation"> 机译：PBX 9502;挖掘;渗透率;扩散性;TATB;
