| 摘要: |
| 采用试验发动机法，对嵌银丝铝镁贫氧推进剂的燃烧特性进行了研究，得到了低压下嵌银丝铝镁贫氧推进剂的燃烧规律，研究了银丝直径和贫氧推进剂配方对嵌银丝发动机燃速的影响。结果表明，嵌银丝贫氧推进剂的燃烧过程由初始工作段、稳定工作段和结束段组成；采用较粗的银丝（0.3mm和0.4mm）可以显著提高贫氧推进剂的燃速；提高贫氧推进剂的基础燃速也是提高嵌银丝贫氧推进剂燃速的有效方法之一。 |

| Abstract: |
| The combustion characteristics of silver-wire embeded fuel-rich propellant grain are investigated. The effect of the diameters of silver wires and the composition of the propellant on the combustion properties is studied. The test pressure-time curves show that the combustion process of silver-embedded fuel-rich grain consiss of initial part, steady part and end part. The silver-embedded fuel-rich propellant grain with coarse silver wire（diameter: 0.3mm and 0.4mm）gives up high burning rate. Furthermore, to increase the burning rate of the fuel-rich propellant is also a good way to increase the burning rate of the silver-embedded fuel-rich propellant grain. |
