Development Tendency and Key Technology of Deep SpaceExploration's Sample Return Capsule

摘要

As the key and fundamental technology of China Lunar Exploration Project, Sample Return Capsule will return to earth from lunar for the first time. This paper introduces the contrast to typical foreign deep space Sample Return Capsule's key performance such as Aerodynamic configuration, overload factor, entry range, stagnation point peak heating base on investigating a great deal of typical deep space sample return missions. Finally, it gives the future development direction of the deep space sample return mission, and offers some proposal for China Lunar Exploration Project.
