卧姿有依托射击条件下的自动步枪动力分析及实验研究

DYNAMICAL ANALYSIS AND TEST STUDY FOR AUTO-RIFLES UNDER THE FIRING CONDITION WITH PRONE POSITION AND SUPPORT

一般情况下，自动步枪在卧姿无依托发射时，连发弹着点向瞄准点的右上方散布；而对于卧姿有依托持枪发射，连发弹着点向瞄准点的左下方散布。本文将对后一种情况进行理论分析，通过建立该发射系统的物理和数学模型，利用数值方法，对系统的发射动力学特性进行讨论，并通过大量的实弹射击实验对模型进行验证。

Generally, the bursting points of impact scatter to the upper and rlght side of the aiming point when the rifle is fired with prone position and without support, the bursting points of impact scatter to the lower and left side with prone position and support. The problems under the later condition are analysed theoretically, the dynamical characteristics of firing are discussed by using numerical method based on physical model and mathematical model of the firing system which ls verlfied by a large amount firing practice tests.
