摘要
为了准确描述电感梯度随增强型电磁推进器尺寸、实际工况下动态电流趋肤深度和温度变化的情况,建立基于动态电流趋肤深度的轨道几何模型,得到了综合考虑装备尺寸和电流的速度趋肤效应的电感梯度解析计算方法.通过多次推进实验对电枢速度进行测试,结果表明:解析计算的电枢速度与实际测试情况相比误差较小,从而验证了该方法的正确性,这不仅可以揭示电感梯度随电流趋肤深度的变化规律,而且能够为预测增强型电磁推进器的电枢速度提供理论指导.
Abstract
In order to accurately describe the influence of inductance gradient on the size of enhanced electromagnetic propulsion,dynamic current skin depth under actual operating conditions,and temperature changes,a model was established based on the geometry of current-diffusing orbitals.An analytical calculation of the inductance gradient that integrates the size of the electromagnetic energy equipment and the velocity skinning effect was obtained.The armature speed was tested through several propulsion experiments.The results show that the error between the calculated armature speed and the actual test one is small,which verifies the correctness of the proposed method.The research in this paper not only can reveal the change rule of inductance gradient with the current skinning depth,but also can provide effective theoretical guidance for predicting the armature speed of the enhanced electromagnetic propulsion.
