【摘要】 本文在分析双石-2、双铅-2、双钴-2、PT-12、171-30五种双基推进剂侵蚀特性基础上,提出一个对各种推进剂普遍适用的p~αv侵蚀准则。常用的流速准则、密流准则、波别多诺斯切夫数准则,都只能适用于某些推进剂,而且它们仅仅是p~αv准则的一个特例。本文还提出了推进剂适用于什么侵蚀准则的判别方法。最后讨论了p~αv准则的内弹道计算方法、计算与实验结果吻合较好。更多还原

【Abstract】 In this paper a new erosive criterion--p~av criterion is presented,based on analgsis of five kinds of double base propellants. This new erosivecfiterion is universally applicable for all kinds of propellants. The crit-erions in common use, such as "velocity criterion", "mass flux criterion","Pobedonostsev number criteoion", are only applied to some propellantsrespectively. Moreover these criterions are a special condition of the p~avcriterion. In this paper, a discrimination method of erosive-burning-crit-erion is also afforded and to which criterion a certain solid propellantwill be suitable. Finally, a calculation method of interior ballistics ofp~av. criterion is discussed, The result of calculalion is in satisfactoryagreement with the resuit of the test.更多还原
