Asymmetrically initiated (AI) warhead has been widely used to strike air targets. To improve the accuracy and power of AI warhead, asynchronous initiation between lines was proposed. The power and dispersion characteristics of prefabricated fragments under different initiation schemes were studied by LS-DYNA simulation. The results show that asynchronous initiation between lines can regulate fragment velocity and its distribution by changing the trajectory and action position of the high-pressure area. The results of preferred strategies under sextile asynchronous initiation are similar to or even better than that of simultaneous initiation under 12 quantiles. The accuracy can be improved from 30° to 15° by setting a single delay of 1.109 μs under sextile initiation. Compared with the single point initiation, the gain of the maximum initial velocity is 19.0-25.3% under the asynchronous initiation strategy between lines. The maximum deviation of fragments orientation azimuth and flight direction are both 1.4°.
