Description

Fight part capable of switching fragment modes, weapon system and control method thereof Technical Field The application relates to the technical field of warheads, in particular to a warhead capable of switching fragment modes, a weapon system and a control method thereof. Background With the rapid evolution of modern battlefield threats, the incoming targets faced by end defense systems exhibit significant diversity and variability. For example, low-altitude burst-prevention FPV unmanned aerial vehicle, patrol projectile and other low-protection targets have the characteristics of large number, high density, strong maneuverability and the like, the interception system is required to have wide area coverage and high hit probability, and anti-tank missiles, rocket-propelled grenades and other hard and other high-protection targets have strong structural strength or local protection capability, and effective damage can be realized only by relying on high kinetic energy and large-quality fragments. The bipolar differentiation of the target protection capability puts an urgent need for dynamic adaptation to the damage mode of the warhead. Currently, warheads employ a fixed pattern of fragment generation, the fragment size and spatial distribution characteristics of which are cured at the stage of manufacture. Specifically, the prefabricated notch is processed on the surface of the warhead shell to control the breaking path under the action of detonation load, the densely arranged notch is favorable for forming a large number of small-mass fragments, the method is suitable for intercepting unprotected or low-protection targets (such as FPV unmanned aerial vehicles and patrol missiles), and the sparsely arranged notch promotes the shell to break into fragments with smaller number and larger mass and is used for resisting high-protection hard targets (such as antitank missiles). However, the existing warhead can only output a single fragment mode in the flight and interception process, and cannot dynamically adjust the fragment size according to the target type of the attack, so that the adaptability of multi-scene combat is obviously restricted. Disclosure of Invention The embodiment of the application aims to provide a warhead capable of switching fragment modes, a weapon system and a control method thereof, so as to solve the technical problems that the warhead can only output a single fragment mode and has poor applicability.
