含高氮化合物的CMDB推进剂的燃烧特性
Combustion Properties of CMDB Propellant Containing High-nitrogen Compounds
摘要
Abstract
3 ,6-Bis(1H-1 ,2 ,3 ,4-tetrazol-5-yl-amino)-1 ,2 ,4 ,5-tetrazine (BTATz ) and 2-nitroimino-5-nitro-hexahydro-1 ,3 , 5-triazine (NNHT) were used as the energetic additives into the composite modified double-base (CMDB) propellants con-taining hexogen (RDX) or hexanitrohexaazaisowurtzitane (HNIW) ,and the influence rule of BTATz and NNHT on the burning rate ,flame ,and morphology of quenched surface of the propellants were investigated .The results show that BTATz can greatly increase the burning rate of propellant and NNHT helps to produce plateau burning effect .After RDX is completely substituted by BTATz or NNHT in the formulation ,the propellant combustion appears the particular dark zone morphology ,which is visibly different from original RDX-CMDB propellant ,and some diffused flame clusters occur on the combustion surface ,which profit from the high burning-rate nature of BTATz and NNHT ,without a melting process as RDX .The flame photos of RDX-CMDB propellants with and without high-nitrogen compound are similar in appearance , the generation of high-temperature carbon particles on the combustion surface is affected by the fusing RDX ,a fewer high-temperature carbon particles are highly unfavorable to improve the burning rate of RDX-CMDB propellant .The ordinary lead-copper-carbon catalyst system also shows the excellent effects on the combustion properties of the propellant ,coopera-ting with the catalyst system and NNHT ,the burning-rate pressure exponent of NNHT-RDX-CMDB propellant reduces to 0 .19 ,decreased by 76% ,and that of NNHT-HNIW-CMDB propellant reduces to 0 .42 ,decreased by 50 .6% .The cata-lyst system is insensitive to BTATz ,NNHT ,and HNIW ,the major catalyzed effect occurs essentially on the double-base propellant combustion surface and the condensed-gas phase closing to the combustion surface ,the combustion surface struc-ture is changed evidently ,and the combustion properties of CMDB propellants are improved finally.关键词
