Heat and aerodynamic protection for returning spacecraft involves empty rocket stage fuel tank as divided casing housing return capsule or recovery vehicle or rocket drive for cost reduction.

摘要

The empty fuel tank (3) of the rocket stage is divided up so the connected parts form a multi-layer casing (5) to house the return capsule or the re-usable spacecraft or the rocket drives etc. This casing provides protection against heat and/or aerodynamics during the recovery flight as distinct from any specifically designed casing and related extra cost.
