Abstract: Mars airbag lander was a complex structure with many critical parameters, extreme environment conditions, many uncertain factors and high reliability requirements. Computational efficiency of simulation was always a bottleneck problem in the processes of optimization design for the Mars airbag landers. Based on parallel and distributed computing technologies of super computing platforms and the multiobjective robust optimization method, a robust optimization design for the complex airbag system was carried out. The results show that the applications of supercomputer platform may greatly improve the robust optimization's computational efficiency in the optimization design, and the reliability of the Mars airbag lander will be highly improved.
