摘要

Abstract >Gel propulsion systems are of increasing interest due to their valuable energetic and safety considerations. In this paper, performance parameters of gelled UDMH/IRFNA bi‐propellant were compared with performance parameters of its liquid bi‐propellant. Fire tests were carried out with combustion chamber pressures of about 1 to 3?MPa and L* values of 89, 127 and 162?cm. The results showed that the suitable L* to obtain best performance for liquid UDMH/IRFNA combination at the mentioned conditions was 127?cm and for gelled UDMH/IRFNA bi‐propellant was 162?cm, although the increase in performance with an increase of L* from 127 to 162?cm for the gel was very low. </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> >凝胶推进系统因其有价值的能量和安全考虑而越来越兴趣。 在本文中,将凝胶化UDMH / IRFNA双推进剂的性能参数与其液体双推进剂的性能参数进行了比较。 用约1至3℃的燃烧室压力进行火试验,L *值为89,127和162Ω·cm。 结果表明,在提到的条件下获得液体UDMH / IRFNA组合的最佳性能为127Ω·cm,对于凝胶化的UDMH / IRFNA双推进剂为162Ωcm,但随着L增加的性能增加 *凝胶的127到162厘米非常低。</ 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>2019年第9期</span><b style="margin: 0 2px;">|</b><span>共6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=Moghaddam Ali Saberi&option=202" target="_blank" rel="nofollow">Moghaddam Ali Saberi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Rezaei Mohammad Reza&option=202" target="_blank" rel="nofollow">Rezaei Mohammad Reza;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Tavangar Saeed&option=202" target="_blank" rel="nofollow">Tavangar Saeed;</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>Malek Ashtar University of TechnologyTehran I.
