| 摘要: |
| 在价电子燃烧模型的基础上,运用分形理论建立了一个崭新的固体推进剂价电子-分形燃烧模型。针对AP颗粒形状不规则的特点,引进分形维数,进行了燃烧模拟计算方法的有关公式推导和编程计算研究,用价电子-分形燃烧模型编制出燃速计算软件。计算结果表明,该模型比价电子模型计算结果更接近实验值,这说明新型的价电子-分形燃烧模型更合理。 |

| Abstract: |
| A valence electrons fractal combustion model based on the valence electrons combustion model was proposed. By using fractal dimension to compensate for the surface roughness of the AP, it is possible to deduce some formulas concerned and make computer programming. The Visual Basic NET is used as the programming tool to calculate the burning rates of the composite solid propellants. The results obtained in this model fit with the experimental results better than those in the previous valence electrons combustion model. This demonstrates the new valence electrons fractal combustion model is more reasonable. |
