摘要： 研究了压强、镁粉含量、固体组分粒度以及氟化物等因素对镁/硝酸钠富燃料推进剂的燃速影响。研究结果表明,镁/硝酸钠富燃料推进剂的燃速随着压强增大而增大,压强增大到一定程度后,燃速下降;燃速随着镁粉粒度的减小而增加;增大硝酸钠颗粒度,燃速降低,燃烧波动性增加;当镁粉含量达到70%时,推进剂的燃速出现最大值。添加氟化物的推进剂燃速值有所降低,随压强变化燃烧规律也发生了改变。

Abstract: Combustion of Mg/NaNO3 fuel-rich propellants had been studied under different experimental conditions.The experimental results showed that the burning rate of the Mg/NaNO3 propellant firstly increases,and then decreases with increasing the pressure.When the content of magnesium powder is about 70% in the propellant,the burning rate of the propellant reaches a maximum.The burning rate of the propellant increases with decreasing particle size of magnesium powders and sodium nitrate.After adding fluoride to the propellant,the burning rate decreases,and the combustion characteristics changes.

Key words: Fuel-rich propellant+;Magnesium powder+;Sodium nitrate;Burning rate
