“中大口径地炮引信”是我军中大口径地面加农炮的主用制式引信。改进该引信的结构,提高它的战术技术性能,对于在适应我国工厂生产现状的条件下,加快武器装备的更新换代具有一定的意义。本文论述了改进该引信的必要性与可能性,提出了改进设计的初步方案。并结合该引信的改进设计,对中大口径地面线膛炮榴弹引信相互通用的可能性进行了初步探讨。 “Large caliber guns” is the main standard fuze of large-caliber ground cannon in our army. To improve the structure of the fuze and improve its tactical and technical performance is of great significance to speeding up the upgrading of the weaponry and equipment under the condition of adapting to the current status of the factory production in our country. This article discusses the necessity and possibility of improving the fuze, and proposes a preliminary plan to improve the design. Combined with the improved design of the fuze, the possibility of using the middle and large caliber ground-mounted grenade-type fuze fuze with each other is discussed.
