The work aims to summarize the current research status of the landing airbag. Firstly, the working principle, advantages and disadvantages of different cushioning airbags were introduced. Then, the calculation methods and performance parameter optimization methods of the two kinds of airbags in finite element analysis, as well as the development of airbag technology was summarized. As a result, the advantages and disadvantages of all kinds of cushion airbag and performance parameter calculation methods were analyzed, and the problems to be solved by airbag technology were summarized. In conclusion, improving pressure active control technology and landing attitude control technology can further improve airbag performance.
