目的 综述国内外回收用缓冲气囊关键技术的研究进展，为缓冲气囊在大型舱体回收中的应用与研究提供基础。方法 通过对国内外研究现状和研究成果的分析和总结，介绍国内外在缓冲气囊的关键技术（气囊充气技术、排气孔爆破压力控制技术、排气孔面积控制技术和气囊增压技术）方面的研究进展，最后对气囊试验验证技术进行分析梳理。结论 国内在回收用缓冲气囊关键技术上的研究，尤其是在大型舱体回收中的应用研究较少，还需要借鉴国外成功经验，进一步深入研究回收用缓冲气囊的关键技术，为缓冲气囊在重型装备和航天器回收中的应用提供支持。

The work aims to summarize the research progress of key technologies of the airbag for recovery at home and abroad to provide a basis for the application and research of the airbag in large-scale cabin recovery. Through the analysis and summary of the present research situation and research results at home and abroad, the research progress of key technologies (gas-charging technology, control technology of airbag venting pressure, control technology of airbag vent area and airbag pressurization technology) of airbag at home and abroad was introduced. Finally, the experimental verification technology of airbag was analyzed and combed. Domestic research on the key technologies of the airbag for recovery, especially the applied research in the large-scale cabin recovery, is few, and such key technologies need to be further studied with reference to foreign successful experiences to provide support for the application of the airbag in the recovery of heavy equipment and spacecraft.
