Abstract

Abstract

Nose shape of projectiles is an important factor influencing the penetration ability. For high speed/ultra high speed kinetic energy penetration of ideal rigid projectiles, this factor is becoming more serious. Based on the classical cavity expansion theory and designing scheme of double-ogival nose, this paper analyses the relationship between nose shape factor and the characteristic parameters of double ogive, and obtains the influence of modified nose projectiles on the penetration performance. It puts forward the design scheme of modified nose penetration body with smaller penetration resistance. The comparison among the results of nose penetration test, proves that this analysis and method are reasonable and feasible, and can be used in judgement for the design of high speed penetrator nose shape.
