摘要
Abstract
A mathematical model on the conversion rate ξ of warhead charge energy to kinetic energy of fragments was established for a typical cylindrical charge.The calculation is basically in good agreement with experimental results.A group of optimization design equations to maximize the kinetic energy of warhead fragments was developed based on this model.If the total quality of warhead is limited,the sufficient condition of which fragments obtain the maximal kinetic energy is that the backfill ratioβ is about √2.If the length-to-diameter ratio of charge is limited,then the sufficient condition is that the backfill ratio is [η+ (η2 +48η) 1/2]/4,in which η is the density ratio of charge and shells.关键词
