空间环境长期演化模型研究

Research Status of Space Environment’s Long-term Evolution Model

摘要:

针对空间碎片对航天器日益凸显的威胁,在明确对空间环境研究方法的基础上,分析了国内外在空间环境长期演化模型方面的研究现状,以LEGEND模型和DAMAGE模型为例,对国外空间环境长期演化模型的机理进行了研究,提出长期演化模型的关键科学问题,并阐述了研究现状；展望长期演化模型的未来研究方向。

Abstract:

Aiming at the increasing threat of space debris to spacecraft, on the basis of clear research methods of space environment, analyze the research status of long-term evolution model of space environment at home and abroad. Taking LEGEND model and DAMAGE model as examples, study the mechanism of the foreign space environment’s long-term evolution model, put forward the key scientific problems of long-term evolution model, and introduce the research status. Forecast the future research direction of long-term evolution model.
