Abstract: Based on the experiments and theoretical analysis, a simplified spacecraft shield design method is developed in this paper, to choose the shield style and begin the preliminary spacecraft shield design A supposed metal particle is produced as the "design" particle to equate the effect made by realized debris The semi-empirical geometrical formulation for specific shield and the orbital debris engineering environment model are also utilized to roughly size the bumper and rear wall of meteoroid/debris shields The results of Whipple Shielding are consistent with that of other methods, so this design method developed is efficient and applied for the realized engineering design work.
