Asymmetrical initiation is an effective way to alter the lethality direction,but the aiming precision is still not enough and it may cause fuze/warhead corporation problems.For more precise control of the lethality elements,numerical simulation is used to study the influence of circumferential delay initiation and axial delay initiation on the cylindrical and hexagonal prism warheads lethality distribution.The results show that as the circumferential initiation delay increases,the aiming direction changes much.The maximum change of cylindrical warhead is considerable,but that of the hexagonal prism warhead is only 2.3° due to structural constraint.The axial ejection angle similarly changes along with the axial initiation delay,and the maximum angle changes of cylindrical warhead and hexagonal prism warhead are 6.6° and 8.4° respectively.The delay initiation of multi-point is proved to be an effective way to re-aim the aiming direction of aimable warhead.
