摘要 火箭制造成本主要由火箭本身、回收修复、组装运输、燃料及重复使用 费用构成，不考虑回收时，单次成本约为 5,000-6,000 万美元。一级助 推器成本约 3,000-4,000 万美元，二级火箭成本约 1,200-1,400 万美 元，整流罩回收后成本降至 600 万美元。 火箭回收后的修复费用在 25 万至 200 万美元之间，主要涉及更换密封 件、垫圈、涡轮叶片，以及燃料箱解压清洁、支架检查和外壳清洗等。 严重损坏可能导致更换整个发动机，增加修复成本。 组装运输到发射台的费用约为 100 万美元，耗时三周。中国制造基地与 发射场距离较远，导致运输和组装成本相对较高。燃料成本约为 35 万 美元，人员设备费用约为 200 万美元，使得单次发射总费用接近 7,000 万美元。 可重复使用技术能显著降低成本。助推器和整流罩的重复使用可将单次 发射费用从 7,000 万美元降至 2000 多万美元，单位载重价格降至每千 克六七千元人民币，大幅低于传统不可回收方案。 Q&A 请介绍一下火箭的成本结构和主要组成部分。 重视火箭核心环节的投资机会 20251228 火箭的成本结构可以分为多个部分，主要包括整流罩、 ...
