The traditional anti‐aircraft and anti‐missile warhead mainly hit the target by fragments or MEFPs. However, these killing elements are only effective for thin‐shell ammunition (10–30 mm), but not for thick‐shell ammunition (>100 mm). This paper proposes an attacking method towards thick moving target by shaped charge jet. Through the analysis of the whole penetrating process between the shaped charge jet and the thick moving target, the paper divides the process into two stages: undisturbed jet penetration and disturbed jet penetration. Based on virtual origin theory, this paper carried out detailed theoretical analysis for each stage and established theory algorithms of changes of cavity when shaped charge jet penetrates the thick moving target, penetration depth of undistributed jet, the lateral velocity of jet and penetration depth contributed by distributed jet. Since the current experimental method cannot accurately analyze the dynamic penetration process of each jet element, in order to verify the theoretical model, a diameter of 66 mm shaped charge was designed, and through the LS‐DYNA software, the jet penetrates steel target with the transverse velocity of 0∼600 m/s was calculated. The study also carried out detailed analysis of the jet tip and tail velocity, the shape of the penetration hole, the lateral velocity of the disturbed jet and the total depth of penetration. At the same time, we combine with the experimental data of E. Marmor et al.[22], to compare with the theoretical results. The calculations are in good agreement with the E. Marmor's experimental datas. The results indicate that shaped charge warhead is an effective method to tackle high speed thick moving target. The theoretical model established in this paper can effectively guide the structural design of the warhead.

“…In the numerical simulation, RDX (hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine) was used as the main charge, and the detonation velocity was set to 8490 m/s. Liu et al [ 20 ] and Wu et al [ 21 ] both studied a theoretical method of calculating the interaction between the shaped energy jet and the target plate during penetration of the target plate through theoretical analysis and a jet penetration test. In the test, 8701 explosives and Comp-B explosives, with detonation velocities of 8390 m/s and 7980 m/s, respectively, were used as internal charges.…”

In guided ammunition, because a shaped energy jet warhead is located behind the control cabin (including the guidance cabin, the steering gear cabin, and the flight control cabin), the penetration order of a shaped energy jet is the control cabin and the target plate. In order to obtain maximum penetration depth by a shaped energy jet into a Q235 steel plate, the penetration performance of shaped energy jets was studied by numerical simulation and experimental verification. Firstly, the penetration performance of a warhead under different conditions at a certain explosion height is studied, which is the penetration performance of a Q235 steel plate with and without the control cabin. Secondly, the numerical simulation results are verified by experimental method. The numerical simulation and experimental results showed that, after penetration of the shaped energy jet warhead into the control cabin, it continued to penetrate the 20 mm-thick Q235 steel plate. At a certain explosion height, the maximum penetration depth of the shaped energy jet warhead into the Q235 steel plate was about 80 mm. Alongside the numerical simulation and experiment, the armor-breaking process of the shaped charge jet was analyzed theoretically. The results show that when the shaped energy jet warhead is located behind the control cabin, although the control cabin will have a certain impact on the penetration ability of shaped energy jet, the penetration performance of the residual jet still has the ability to penetrate light armor.
