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.
