Abstract:	Aiming at the protection of indirect effects such as interference and damage to electrical equipment inside a rocket caused by lightning, this paper analyzes some common reinforcement methods for the electrical equipment in the rocket. Based on the way that these typical devices are interfered by lightning electromagnetic pulse, this paper also establishes a conducted interference model and a radiation interference model for the design of rocket anti lightning reinforcement. On this basis, a minimum mass increment design method based on particle swarm optimization (PSO) for lightning indirect effect resistance of the electrical equipment in the rocket is proposed. The optimization results show that the proposed method can control the minimum mass increment of the rocket on the premise of meeting the protection indexes, which is of great engineering significance to improving the overall performance of the rocket.
