以静态燃速预示固体发动机燃速

Prediction of burning rate of solid motor by static burning rate of strands

对同一工艺条件下大量的药条燃速、φ127 mm发动机燃速和全尺寸发动机燃速进行了测试和研究,对不同截面尺寸的药条燃速测试结果和精度进行了比较。结果表明,当选择合理的药条截面尺寸时,药条燃速与全尺寸发动机燃速间具有满意的相关性,可对全尺寸发动机燃速进行预示。研究结果可用于固体发动机工程实际。

Burning rates of a lot of strands, φ127 mm solid motors and full-scale solid motors under the same process conditions were measured and analyzed. Measurement results and accuracy of the burning rates of the strands with different cross section sizes were compared, The results show that there is a good linear correlation between the burning rate of the strands with proper cross section size and full scale solid motors;the burning rate of the strands can be used for predicting the burning rates of full-scale solid motors. The investigation results can provide reference for engineering application of solid motors.
