| 摘 要： | 减速伞拉出时间是描述低空低阻伞弹弹道特性的重要参数之一,在研究某低空低阻伞弹投弹表编拟方法时发现,拉出时间的测试数据有较大误差,制约着其它弹道参数的正确确定和投弹表的编制精度。笔者利用实测坐标数的差分特性对实测拉出时间进行了修正,该方法有利于提高投弹表编制精度和改进拉出时间的测试手段。

| Abstract: | The draw-out -time is one of the most important ballistic parameters of the low-drag parachute bomb. It has been found in studying up on a new method of making the bombing table for a certain low-drag parachute bomb that the measuring error on the draw-out-time is much bigger which has great influence upon making sure of the other ballistic parameters and the accuracy of making the bombing tables. In this paper, the test data of the draw-out-time is been corrected by using the method of coordinate difference. |
