The rapid increase of space activities has led to an urgent problem of space debris. Active debris removal based on flexible nets is promising in the control of space debris. Here the application of electromagnetic launch in the deployment of flexible net is considered. A lumped-parameter electromechanical model of the coil launcher is developed with emphasis on the analysis of the magnetic field involved. Analytical solution to the magnetostaic problem is given based on eigen-expansions on decomposed domains. Dynamic behavior of the iron slug is then computed and analyzed with optimal initial position of the iron slug found. Influence of the capacitance of the super-capacitor upon the launch performance is also investigated. Results are discussed and future directions of investigations are provided.
