A Model of Calculating Hitting Point Parameters of Fragment in Warhead/Target Encounter
摘要
Abstract
To calculate hitting point parameters of fragment accurately, a calculation model was proposed to get all hitting point parameters by numerating fragments only once. In this model, the shot-line technique, which took the velocity fade into account, was adopted to describe the fragment trace. Three kinds of existence conditions of solutions, which were corresponding to three kinds of motion relationship between single fragment and target face, were obtained by analyzing the model. Taking the steel fragment for an example, the effects of warhead/target encounter parameters and fading coefficient of fragments velocity on hitting point parameters were discussed quantificationally. Results show that,the hitting point parameters are sensitive to target velocity and static fragments velocity, but insensitive to missile velocity.关键词
