摘要
战斗部头部形状是影响其侵彻能力的重要因素,对于理想刚性战斗部在高速侵彻时,头部形状的影响更加突出,为提升作战技能,基于传统空腔膨胀理论,结合战斗部头部减阻优化设计思路,对影响战斗部侵彻阻力的关键系数N^*进行分析,获取了弹头形状系数与头部刻槽参数的关系,分析了关键参数对头部刻槽战斗部侵彻性能的影响规律,提出了一种侵彻阻力较小的头部刻槽战斗部设计方案。经理论分析计算,结果表明该头部刻槽战斗部方案可用于指导后续战斗部设计。
Nose shape is an important factor to influence the penetration performance.For high/ultra-high speed kinetic energy penetration,this factor is more serious.Based on the classical cavity expansion theory and design of low resistance,the relationship of nose factor N^*and grooved-tapered parameter is analyzed,and the influence rule of grooved-tapered penetration performance is obtained.The design of grooved-tapered with smaller penetration resistance is put forward,and the analysis results are proved reasonable and feasible by calculation,which can be used in judgment of the design of high speed penetrator nose shape.
