现行歼击机空战激光模拟训练器为歼击机空中射击训练提供了新手段。但它是以激光模拟瞄准线为基础的,与实弹打靶差别较大。研制能以光代替机炮弹丸、不需实弹打靶就可全面考核空战训练情况的新型空战激光模拟训练器,可把空战训练提高到新水平。本文提出了以激光模拟机炮弹丸的一种理论,推导出有关的公式,提出几点简化实施设想。 The current fighter air combat laser simulation trainer provides a new means for fighter air shooting training. But it is based on the laser simulation line of sight, and the difference between live and target shooting. The development of a new type of air combat laser simulator that replaces the cannonball with light instead of a live bullet target can comprehensively assess the status of air combat training and raise the training of air combat to a new level. In this paper, a theory of laser simulator gun projectile is proposed, the relevant formulas are deduced, and some simplifications are put forward.
