【摘要】 随着现代战争形势的变化和国际局势的发展,特种作战与特种任务也成为维护国家安全,保障国家利益的重要手段,在执行特种任务时,需要一种可以隐蔽携带的特种武器。本文通过分析国内外注射武器系统的发展现状,结合实际任务需求,设计了一种隐蔽式的注射武器系统,并对其相关特性进行了研究。根据要求,设计了一种由尾翼稳定的可更换药管的注射弹和伪装为移动电源的发射器组成的武器系统。为了保证设计的注射弹具有较好的飞行稳定性,通过FLUENT软件对注射弹的气动特性进行了仿真计算,得到了注射弹在不同马赫数、不同攻角下的气动参数,计算结果表明设计的注射弹具有较好的静稳定性,并研究了风帽形状、尾翼、针头长度等弹体外形对其气动特性的影响规律。建立了压缩气体发射注射弹的内弹道方程,测量了发射摩擦阻力参数,并计算得到了发射内弹道过程的曲线,进而结合注射弹的气动参数计算得到了外弹道特性。通过LS-DYNA软件对注射弹侵彻明胶过程进行了仿真,对注射弹击发过程进行了计算,通过试验测量、ANSYS有限元仿真、理论计算等方法对注射弹注射过程进行了分析,校核了关键药管的强度,验证了设计的注射弹满足相应的指标要求。通过试验验证的方法,验证了注射弹的飞行稳定性和穿透性。本论文设计的隐蔽式注射武器系统具有一定的实用价值,文中的研究方法和相关结论对隐蔽式特种武器的进一步研究提供了参考和理论依据,具有较强的参考价值。

【Abstract】 With the changes in the modern war situation and the development of the international situation,special operations and special missions have also become important means of safeguarding national security and safeguarding national interests.When performing special missions,a special weapon that can be concealed and carried is needed.This paper analyzes the development status of injection weapon systems at home and abroad,and combines the actual task requirements to design a concealed injection weapon system and researches its related characteristics.According to the requirements,a weapon system is designed which consists of a replaceable medicine tube-injected projectile with a tail fin and a launcher disguised as a power bank.In order to ensure that the designed projectile has good flight stability,the aerodynamic characteristics of the projectile are simulated by FLUENT,and the aerodynamic parameters of the projectile at different Mach numbers and different angles of attack are obtained.The calculation results show that the designed injection projectile has good static stability,and the influence of the shape of the projectile,such as hood shape,tail,and needle length,on its aerodynamic characteristics is studied.The internal ballistic equation of the compressed gas-fired injection projectile was established,the launch frictional resistance parameters were measured,and the curve of the internal ballistic process was calculated.Then the external ballistic characteristics were calculated by combining the aerodynamic parameters of the injection projectile.The LS-DYNA software was used to simulate the penetrating process of projectile into gelatin,and the process of firing was calculated.The injection process of the projectile was analyzed through test measurement,ANSYS finite element simulation,theoretical calculation and other methods and the strength of key injection tube was checked,where by the specifications satisfaction of the designed injection projectile was valiated.The experimental verification method verified the flight stability and penetrability of the projectile.The concealed injection weapon system designed in this paper has a certain practical value.The research methods and related conclusions in this paper provide a reference and theoretical basis for the further research of concealed special weapons,and have a strong reference value.
