摘要:
为了研究铝粉含量对含CL-20改性双基推进剂燃烧性能的影响,采用静态燃速仪测试了CL-20/Al-CMDB推进剂的燃速,拟合了燃速公式并分析了CL-20/Al-CMDB推进剂的燃烧过程及铝粉对燃速的影响。结果表明, 6~10 MPa下推进剂的燃速与铝粉含量的平方(wAl2)呈相互平行线性关系,10~16 MPa下速率常数(k)在一条直线上,说明CL-20/Al-CMDB推进剂的燃烧反应速度仅与Al的含量有关;进一步分析燃烧表面暗区Al表面积大小对推进剂燃速的影响,发现4~11.5 MPa时Al在暗区吸热导致燃速下降,11.5~16 MPa下Al在火焰区燃烧产生的热量对暗区的热反馈抵消了其吸收的热量,使燃速增加;Al在燃烧表面的吸热过程对燃速的影响因素定义为Al的惰性热稀释。
Abstract:
To investigate the effect of aluminum powder content on the combustion performance of CL-20 modified double-base propellant, the burning rate of CL-20/Al-CMDB propellant was measured by static burning rate test instrument, the burning rate formula was fitted and the combustion process and the effect of aluminum powder on the burning rate of CL-20/Al-CMDB propellant were analyzed. The results show that burning rates of the propellant under 6-10 MPa are in parallel with the square value of aluminum powder content (wAl2), the rate constant (k)under 10-16MPa is in a straight line, indicating that the combustion reaction rate of CL-20/Al-CMDB propellant is only related to the content of Al. The effect of surface area size of Al in dark zone of combustion surface on the burning rate of propellant was further analyzed. It is found that the endothermic effect of Al in dark zone makes the burning rate decrease at 4-11.5 MPa, under 11.5-16 MPa, the heat generated by Al combustion in flame zone offsets the heat absorbed by the heat feedback in dark zone, making the burning rate increase. The factor influencing the endothermic process of Al on combustion surface is defined as inert heat dilution (IHD) of Al.
