摘要
研究了不同粒径(1μm、3μm、5μm)与含量的镍粉对RDX-CMDB推进剂燃烧性能的影响。燃速测试结果表明:镍粉能有效提高RDX-CMDB推进剂的燃速。1~10MPa下,添加1.5%的3μm镍粉的RDX-CMDB推进剂燃速最高。火焰结构照片显示RDX-CMDB推进剂体系中加入镍粉,燃烧火焰面积大大增加,且降低了暗区厚度。1MPa下的燃烧波温度分布曲线结果显示镍粉的加入对推进剂的燃面温度无较大影响,但是绝热火焰温度大幅度地提高。
The influences of particle size and content of nickel powder on combustion performance of RDX-CMDB propellant were investigated. The results showed that nickel powder could improve the burning rate of RDX -CMDB propellant significantly. The burning rate was the highest when adding the amount of 1.5% nickel powder with 3prn under 1-10MPa. The combustion flame areas increased greatly when adding nickel powder, meanwhile, the thickness of dark area was decreased. The combustion wave temperature distribution were studied under 1MPa, the results revealed that combustion surface temperature T~ did not change obviously, however the adiabatic flame temperature increased substantially as adding nickel powder.
