| 摘要: |
| 为了以尽可能少的试验对固液混合发动机的燃面退移规律进行辨识,采用在一发试验中适当调节工作参数的方式,并结合瞬时燃面退移速率求解方法,总结出了一套固液混合发动机燃面退移规律辨识方法进行了试验验证,结果表明:采用二维药型的固液混合发动机,通过一发试验即可较准确地掌握其燃面退移规律,还可应用于其它同种类型的固液混合发动机内弹道性能预测。 |

| Abstract: |
| A regression rate identification method was developed based on adjusting the working parameters of a single test and solving the transient surface regression rate.This method has been validated by experimental results.The results show that surface regression rate can be obtained with good accuracy from one test by means of 2D grain configurations and this method can be applied to the performance prediction of other hybrid motors of the same type. |
