Summary:The embodiment of the invention provides a corrosion-resistant systematic design method for a spaceflight fastening connection system, and the design method comprises a compatibility evaluation and precise design method for a fastener and a new-generation liquid propellant. The method is realized based on a compatibility soaking test of a fastener and a new-generation liquid propellant, compatibility evaluation of the fastener and the new-generation liquid propellant and a test analysis method, and the design method further comprises a multilayer heterogeneous alloy multiphase connection galvanic corrosion rate evaluation and precision matching design method of the fastening connection system. The method is realized on the basis of a two-phase multi-combination electrochemical test of the fastening connection system and a force, heat and electrochemical coupling field simulation analysis method of the fastening connection system based on COMSOL software, the multi-layer heterogeneous alloy comprises a fastene
