Abstract
Reusable Launch Vehicles(RLVs)represent a key technology for increasing launch frequency and reducing launch costs,with the selection of metallic materials and manufacturing technologies for the recovery system serving as the foundation for ensuring reliability and reusability.This paper analyzes the material performance requirements for two key RLVs recovery components:Vertical landing mechanisms and grid fins.For vertical landing mechanisms,this paper systematically elaborates on the property characteristics and application progress of metallic materials,including load-bearing structural materials with ultra-high strength(such as ultra-high-strength steels and high-strength titanium alloys)and crushable buffer materials with energy-absorbing capacity(such as aluminum honeycomb and NiTi shape memory alloys with lattice architecture).For grid fins,this paper highlights light-weight structural materials such as aluminum and titanium alloys,and compares advantages of key manufacturing processes,including spliced welding,precision casting,and additive manufacturing.Based on typical engineering application,this paper reviews the current state of metallic materials and associated manufacturing process used in recovery system,and provides an outlook on future development trends.This work seeks to provide references for material selection and process optimization of RLVs recovery systems in China.关键词
