| 摘 要： | 研究了Al粉的含量以及纳米级Al粉(粒径<100nm)和普通Al粉(粒径12～15μm)对浇铸复合改性双基(CMDB)推进剂能量性能、燃烧性能的影响,并探讨了该类推进剂的燃烧机理。结果表明,随着Al粉含量的增大,CMDB推进剂的能量提高,Al粉的最佳添加量为8%;当普通粒径Al粉与纳米Al粉以1:1级配时,CMDB推进剂低压段燃速大幅提高,7～15MPa压强范围内的压力指数降至0.45以下。

| Abstract: | Effect of content and granularity of aluminum powder(Al)on the combustion characteristics and energy properties of casted CMDB propellants were studied,and the combustion mechanism was also investigated.Results show that energy of the CMDB propellant increases with the increasing of Al content,and optimal Al content is 8%.The burning rates of the CMDB propellant at lower pressures increase in a great extent when the proportion of common Al and nano Al is 1:1,and the burning rate exponents of the propellant under 7-15 MPa decrease to lower than 0.45. |
