“…Among all the existing landing attenuation systems, the airbag is the most widely used with wide adaptability. Hence, there have been several successful applications such as the "Mars Pathfinder," "Spirit," and "Opportunity" based on the omnidirection nonvented airbag landing attenuation system [1][2][3]. This kind of attenuation system is not sensitive to the orientation of the payload on landing, and it allows successful landings on a wider range of surfaces or under difficult conditions [4].…”

The inflatable buffer landing system, such as the airbag, has been widely used for deep space exploration as a low-cost entry. The impact performance of an airbag landing attenuation system on Mars had to be proven through cushion testing on Earth. In this paper, a design method for the airbag landing attenuation system on Earth is proposed based on similarity relation. With this method, the impact response of the spherical airbag landing attenuation system is derived based on assumptions, and the principal factors have great influence on the impact response of the landing system have been proved. Then, the similarity relation between the full-scale airbag landing attenuation system in the Martian atmosphere and its Earth prototype is obtained through theoretical derivation. Finally, the proposed similarity relationship has been tested on several ground prototypes by FEA. The results of the study show that the Earth prototype by the developed design method is capable of predicting the impact response with good accuracy.
