摘　　要：研究分析了欧洲航天局天地往返运输系统之载人飞船返回舱CTV的气动特性,并与第一代联盟号飞船返回舱的气动特性作了对比研究。该返回舱为钝双锥外形,与联盟号飞船返回舱相比,它具有升阻比高、机动性强、稳定性好等特点。本文还对两类返回舱的气动热特性、防热材料重量、飞行弹道及通讯中断问题进行了对比分析研究。The general aerodynamic characteristics of European Crew Transfer Vehicle (CTV), which is designed for the manned orbittoearth transfer system, are discussed and summarized, and the comparison with that of the first generation of manned reentry capsule Soyuz is investigated. Unlike Soyuz, CTV is of blunt biconic shape with compound control system of aerodynamics and reaction jet, has higher lifttodrag ratio, better maneuverability and stability. The aerothermodynamic environments, the weight of thermal protect system, the reentry trajectory performance and communication blackin and blackout performance are illustrated and analyzed. 
