Title    Analysis of Damage to Reactive Armor by Shaped Jet     

Abstract ERA can reduce the ability of the jet obviously。 This paper discusses the development of the ERA and the current research status。 Papers explained the mechanism of the ERA interfering the jet, including fly board and detonation products。

Papers set up the theoretical model of the single ERA on the jet interference through the theoretical analysis and combined with literature, and Paper obtained the typical factors influence about jet molding through numberical simulation for many times。 Using the orthogonal optimization design obtained the basic parameters of the high explosive anti-tank cartridge。 So the major study context in this paper includes those:

(1)The ERA interference model of jet is studied。 In according to collating of jet penetration theory, which get the jet penetration theoretic model and fly aboard armors interference model of the jet on the sidelines of the escape。

(2)The angle, the thickness of the shaped charge liner, charging high impact jet molding simulation analysis is studied。 Based on keeping other parameters constant for numberical simulation, it gets the typical factors influence of jet velocity, jet length, jet diameter through changing the parameters of a particular。     

(3)It is studied that can get the optimal structure of shaped charge warhead by orthogonal optimization design, and established  the jet penetrating the model of the tilt 68°ERA 。Paper explained the simulation results according to the simulation model of the jet flowing the ERA。
