Influence of skin depth on inductance gradient of enhanced electromagnetic propulsion
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.
