摘要:
为探究锆粉含量对高能推进剂能量特性的影响规律,利用热力学计算软件CEA分析了不同锆含量的Zr/Al基NEPE推进剂和Zr/Al基叠氮高能推进剂的能量特性;通过计算这两种推进剂的燃烧温度、密度、比冲和密度比冲等能量特性参数,得到了锆含量对推进剂能量特性参数的影响规律,并将结果与ZrH2/Al基高能推进剂进行对比分析。结果表明,随着Zr含量增加,NEPE推进剂的燃烧温度和比冲均呈下降趋势,密度比冲持续上升,但考虑推进剂的能量特性和高燃温条件下的不稳定燃烧,认为在推进剂中添加质量分数3%~5%的Zr粉较适中;随着Zr含量增加,叠氮高能推进剂的燃烧温度和比冲呈现先增后减的趋势,且分别在Zr粉质量分数为6%和3%左右达到最大值,推进剂密度比冲持续上升。ZrH2/Al基推进剂的能量性能低于Zr/Al基推进剂的。
Abstract:
To investigate the influence law of zirconium powder content on the energy characteristics of high-energy propellant, the analysis investigation of energy characteristics for Zr/Al-based propellant and Zr/Al-based azide high-energy propellant with different zirconium content was performed by thermodynamic calculation software CEA. By calculating the energy characteristics of the two propellants, such as combustion temperature, density, specific impulse and density specific impulse, the influence law of zirconium content on the energy characteristic parameters of the propellant was obtained, which was compared with ZrH2/Al-based high energy propellant. The results show that with the increase of Zr content, the combustion temperature and specific impulse of NEPE propellant decrease, but the density specific impulse continuously increases. Taking into account the energy characteristics of the propellant and the unstable combustion at high combustion temperature conditions, considering that the addition of Zr powder with mass fraction of 3%-5% in propellant is moderate. With the increase of Zr content, the combustion temperature and specific impulse of azide high-energy propellant show a trend of increasing first and then decreasing, and reach a maximum when the mass fraction of Zr powder is 6% and 3% respectively and the propellant density specific impulse continues to rise. Meantime, it was also found that the energy characteristics of the ZrH2/Al-based propellant is lower than that of the Zr/Al-based propellant.
