阅读说明：本技术 定装枪弹发射药内燃式空心装药结构 (Internal combustion type hollow powder charging structure for loading and discharging powder of bullet ) 是由 姚树 于 2019-12-23 设计创作，主要内容包括：本发明为″定装枪弹发射药内燃式空心装药结构″,是解决定装枪弹发射药溢出弹筒进入枪管燃烧问题的技术方案。本设计的优点：一是发射药的燃烧都在弹筒内进行,基本没有未燃烧的发射药进入枪管,可以有效避免枪管烧蚀,并使弹丸在枪管中受力均衡运动稳定。二是弹筒抛壳可以带走全部残渣和更多热量,从而持续保持枪管清洁并减轻枪管发热。不仅延长枪管寿命,还能拓宽枪管材料的可选择范围。三是可以增加发射药燃烧面,提高发射药的燃烧速度和燃烧率,提升枪的性能。本设计构造简单新颖,生产制造容易实现,必要时向发射药中适量添加高可燃性粘合剂即可制备。本结构适用于定装枪弹和定装炮弹及其它定装弹药。(The invention relates to an internal combustion type hollow charge structure for fixing the propellant powder of a bullet, which is a technical scheme for solving the problem that the propellant powder of the bullet is overflowed from a bullet barrel and enters a barrel for combustion. The advantage of this design: firstly, the burning of propellant powder is all gone on in the barrel, and the propellant powder that does not basically not unburned gets into the barrel, can effectively avoid the barrel to ablate to make the pellet atress balanced motion stable in the barrel. And secondly, the ejection of the cartridge can take away all residues and more heat, so that the barrel is kept clean continuously and the heat of the barrel is reduced. Not only prolongs the service life of the gun barrel, but also widens the selectable range of the materials of the gun barrel. Thirdly, the combustion surface of the propellant powder can be increased, the combustion speed and the combustion rate of the propellant powder are improved, and the performance of the gun is improved. The design and the structure are simple and novel, the production and the manufacture are easy to realize, and the propellant powder can be prepared by adding a proper amount of high-flammability adhesive into the propellant powder when necessary. The structure is suitable for loading gun ammunition, shell and other ammunition.)
