专业,这就说的通了。苏系飞船与美系飞船防热方案不同,烧黑程度不同。东大飞船较黑也说通了。点赞 【 在 EricCartman 的大作中提到: 】 : There are two main reasons why the Apollo reentry capsule appeared less black than the Soyuz capsule after landing: : Heat Shield Material: Both capsules relied on heat shields to absorb the tremendous heat generated during atmospheric reentry. However, they used different materials: : Apollo: Used an ablative heat shield made of a resinous material filled with millions of tiny fiberglass spheres. This material burned away during reentry, leaving a lighter brown or tan colored char on the surface. : ................... -- FROM 117.136.38.*
