    摘要: A method for evaluating a damage power of confined explosion, includes: determining a size of a confined case and a thickness of a target plate according to a requirement of evaluation on damage effectiveness of a warhead to establish an explosive damage effectiveness evaluation platform; calibrating parameters of the platform with a series of confined explosion tests of trinitrotoluene (TNT) bare charges in the case to form a relational map, in which a deflection of a mid-point of the target plate changes with a charge mass; obtaining a deflection of the mid-point of the target plate by detonating different warheads, forming different detonation atmosphere and forming different venting configuration in the case, and performing interpolation through the map to obtain an equivalent bare charge as an evaluation index. The method quantitatively evaluates the damage effectiveness of the warhead, and is not limited by the damage component.

    摘要: A method includes determining a perforation tunnel geometry of a perforation tunnel in a solid sample, the perforation tunnel created by activating a shaped charge in proximity to the solid sample. The method also includes performing a first flow test on the solid sample and creating an analog aperture having an aperture geometry in a solid sample analog of the solid sample, wherein the aperture geometry and the perforation tunnel geometry satisfies a similarity threshold. The method also includes performing a second flow test on the solid sample analog and determining a shaped charge effect based on a comparison between a second flow test result and a first flow test result.

    摘要: A modular constructed, standardized test device for simulating a spin stabilized projectile which is fired from a barrel having rifling grooves, comprised of the bolted together, keyed to transfer spin, modular components of replaceable rotating band, replaceable front end and back end, and filler sections for further simulation of other components. The front end has an interior recessed area which allows for a selective integration of a threaded fuze or an aerodynamic, electronic, or other structure and the rear end has a crimp groove for selective attachment of a cartridge case, and aerodynamic or other structure to mimic the rear geometry of a projectile for testing purposes.

    摘要: The invention relates to a test and/or practice ammunition having at least one projectile with a projectile head and a fin which can be found at the end of the projectile for example or a projectile with a projectile base and a projectile ogive. A cartridge shell is used to receive a drive and has a shell base, wherein an interface is attached in or on the shell base. The test and/or practice ammunition is characterized by a programmable fuze which is arranged in the projectile head or the projectile ogive. The projectile head/projectile ogive is equipped with at least one fuze amplifier and an electronic fuze system and optionally a separating charge.
