Abstract

本发明公开一种双向整流炮弹弹头,包括弹头头、弹头体、弹头尾、定向翼、承力托罩、穹窿底、通气孔和崩裂缝。其特征是将弹头尾端设计为与弹头头相似的流线椎体,并设置横向径值小于弹头体的定向翼,在炮弹头与炮弹体之间设置承力托罩。承力托罩为与弹头体横向等径的圆筒,上端罩封弹头尾、下端罩封炮弹体上口、下中部设置穹窿底。本发明与现有技术相比,双向整流的弹头阻力更小、定向翼使弹头飞行更稳定,穹窿底可接受炮膛内爆炸产生的更多动能,使弹头投射距离更远更准确。同时可为火炮和炮弹的创新改造和发展提供更大空间和前景。

Description

双向整流炮弹弹头
一、技术领域:
本发明涉及武器弹药制造,具体的说是一种双向整流炮弹弹头。
二、背景技术:
作为远距离投射破坏性、杀伤性爆炸物的大炮,在现代战争史上发挥了独特和巨大的作用,伴随科学、技术的发展和进步,火箭和导弹延伸和扩展了大炮的功能,部分取代和削弱了大炮在战争中的作用和地位,但是作为随军而动,配合一线战场攻城掠地、滩头防御更具随机性和目标性,区域内的规模化效应作用,大炮仍是不可替代的,在相当长的一段历史时期内炮兵作为军事序列的建制仍会存在下去。
众所周知,大炮是依赖炮膛内的定向受控爆炸一次性提供动力完成弹头发射的,为了使弹头能够最大限度的接受炮膛爆炸所产生的能量,弹头的尾部多设计为平面或内凹面结构。这种结构形态在接受更大一次性动能的同时是需要付出弹头离膛后飞行全程所形成的尾部真空区造成的反向拉力为代价的。
三、发明内容:
本发明的目的是针对现行炮弹弹头造型存在的问题和不足,提供一种符合流体气动原理并设有定向翼的双向整流炮弹弹头。
本发明的目的是通过以下技术方案实现的:
一种双向整流炮弹弹头,包括弹头头、弹头体、弹头尾、定向翼、承力托罩、穹窿底、通气孔和崩裂缝,其特征是将弹头尾设计为与弹头头相似的流线型锥形,并设置外径小于弹头体,后端弧形的定向翼。在炮弹头与炮弹体之间设置承力托罩。承力托罩为与弹头体横向等径的圆筒,上端罩封弹头尾部,下端罩封炮弹体上口、下中部设置与定向翼弧形后端相匹配的穹窿底。穹窿底上设置数个通气孔,上部侧壁留置若干条崩裂缝。
所述的双向整流炮弹弹头,其特征是炮弹头、承力托罩和炮弹体设计为一体结构,或炮弹头与承力托罩组合,或承力托罩与炮弹体组合的分体结构,采用承力托罩与炮弹体组合的分体结构时其穹窿底上不设置通气孔,罩壁上不设置崩裂缝。
所述的双向整流炮弹弹头,其特征是延长炮弹体上口长度包封双向整流炮弹弹头的弹头尾,弹头尾与炮弹体装药间设置游离的穹窿底。
所述的双向整流炮弹弹头,其特征是对定向翼作螺旋曲线设计。
本发明的双向整流炮弹弹头与现有技术相比,具有结构简单、制造容易、气动阻力更小、投送距离更远、飞行过程更稳定等特点,以外还具有以下显著优点:
1、对炮弹弹头进行双向锥形的整流处置,消除了炮弹头飞行过程中尾部的真空区,最大限度减少了负向气阻,使相同质量的炮弹头射程更远。
2、穹窿底的设置,使炮弹头接受炮弹体爆炸动能面积更大、能量更多、出膛后脱落、不增加炮弹头重量。
3、定向翼的设置,使炮弹头飞行过程更稳定、弹道可控度更大、目标精确。
4、定向翼后端设计为与穹窿底相匹配的弧形,可有效均衡穹窿底与炮弹头间力的传递。
5、通气孔和崩裂缝的设置可使炮弹头、承力托罩和炮弹体一体设计、或炮弹头与承力托罩组合设计模式的弹头,在离炮后,由于内外压差原因分离承力托罩。
6、对定向翼作螺旋曲线设计,使滑膛炮管也可发射具有陀螺稳定性的弹头。
7、对弹头、弹体和承力托罩一体、分体或组合的模式,对定向翼形态选择等,都可为炮弹和炮管的创新和发展提供更多空间和可能。
四、附图说明:
附图1为双向整流炮弹弹头的侧面结构示意图。
附图2为双向整流炮弹弹头的承力托罩横断面示意图。
图中:1弹头头、2弹头体、3弹头尾、4定向翼、5承力托罩、6穹窿底、7通气孔、8崩裂缝。
五、具体实施方式:
下面结合说明书附图对本发明的双向整流炮弹弹头做以下进一步详细说明:
如图1所示,本发明对弹头尾3进行与弹头头1相似的流线锥形设计。并于弹头尾3的周边设径值小于弹头体2的定向翼4,定向翼4的尾端设计为内凹弧形。承力托罩5为与弹头体2横向等径的圆筒,上端罩封整个弹头尾3,下端罩封炮弹体上口,下中部设置与定向翼4尾端弧形匹配一致的穹窿底6。穹窿底6上设置与定向翼4数目相等的通气孔7,承力托罩5壁的上端设置与定向翼4数目相等与通气孔7错位的崩裂缝8。
除说明书所述的技术特征外,均为本专业技术人员的已知技术。
