Study on the evaluation of the execution of super high velocity fragment / 第三军医大学学报

ABSTRACT

Objective　To provide experimental basis for the weapon design by means of observing the injury by super high velocity fragments. Methods　Nine male Huanan dogs were wounded by super high velocity aluminium bullet shot from an explosive gun with the energy of 15 360,12 643 and 8 144 J respectively, the degree of injury of local tissues and the pathological changes of main organs were observed. Results　The injury degree of local tissue wounded by the super high velocity fragment of 15 360 J was similar to that of 8 144 J, and was more severe than that of wound by 12 643 J. Conclusion　The injury degree is closely related to the mass and the momentum of the super high velocity fragment, the more the momentum is,the greater the execution is. No significant relationship exist between the injury degree and the energy.
