Abstract

In order to explore the influence of isosceles trapezoid cross-section shape on the jet forming, the numerical simulation research on jet forming of shaped charge with isosceles trapezoid cross-section was carried out, and the jet forming of two kinds of shaped charge with isosceles trapezoid cross-section were obtained by the pulse X-ray photography test. The results showed that the propagation of detonation wave and the crushing process of liner of shaped charge with isosceles trapezoid cross-section are non-axisymmetric, and the forming jet has a certain lateral offset phenomenon. The lateral deflected jet is composed of dispersed fluid and has lateral velocity. The bigger the characteristic number of the isosceles trapezoidal cross-section shape of shaped charge, the greater the lateral offset length of the jet, the more dispersed the jet, and the greater the lateral velocity of the jet; 26 μs, the lateral offset length of the jet formed by the shaped charge with the characteristic number of the isosceles trapezoid cross-section shape is 3.7 increases by 128% compared with the jet formed by the shaped charge with the characteristic number of 1.0, and increases by 214% at 36 μs.

Key words： isosceles trapezoid cross-section shape; shaped charge; jet forming; X-ray test
