KP对硼富燃料推进剂燃烧性能的影响

Combustion of Fuel-Rich Based on Boron Solid Propellant with KP

摘要:

用差示扫描量热(DSC)和热重分析法(TGA),研究了含KP的硼富燃料推进剂的热分解特性,并测量了推进剂燃速。实验结果表明,KP有助于含硼推进剂的点火是因为钾盐的存在,增加了硼的反应活性,使热分解低温段的放热量显著增加。

Abstract:

The pyrolysis behavior and combustion characteristics of the fuel rich based on boron propellant with KP have been studied by thermal gravimetry analysis (TGA) and differential scanning calorimeter (DSC). The results show that potassium saline increases reactive activity of boron, and increases the released heat in the low temperature sect of the propellant’s pyrolysis, so KP improved the ignition peculiarity of the propellant.
