为研究燃速与燃烧波特征量之间的相关性,采用在推进剂内埋设微型热电偶技术,测得了低燃速低燃温双基推进剂的燃烧波结构,并通过数据处理获得了燃烧波的特征量值,包括表面温度、火焰温度、暗区厚度、凝聚相温度梯度和气相嘶嘶区温度梯度.不含催化剂的基础配方燃速随表面温度增大而增大;加入催化剂的配方产生麦撒燃烧,表面温度比基础配方的表面温度有所增加,燃速与表面温度不再是单一的线性关系.火焰温度随压强增大而提高,其与燃速没有明显相关性.结果表明: 低燃速低燃温双基推进剂的燃速与燃烧波特征量之间不仅存在线性关系,还存在非线性关系.分析认为是催化剂改变了低燃速低燃温推进剂的燃烧波结构所致.

To study the relationship between the burning rate and the characteristic value of combustion wave,the combustion wave structure of double-base propellant with low burning rate and low flame temperature were obtained by using the technology of imbedded minimized thermal couples into propellant,and the experimental data were calculated and the characteristic value of combustion wave,the surface temperature,the dark zone thickness,the temperature grades of condensed phase and gas phase fizz zone,were obtained. Burning rate of propellants without catalysts increases with the surface temperature increasing,and the surface temperature of propellants with catalysts is higher than that of propellants without catalysts. Flame temperature enhances with increase in pressure,and there is not necessary relationship between flame temperature and burning rate. Results show: the relationship between the burning rate of the said double-base propellant with low burning rate and low flame temperature and the characteristic value of combustion wave is rather complex,and there are linear and non-linear relationships when combustion performance changes. The reason is that combustion wave structure is changed with catalysts.
