Risk assessment and sensitivity analysis of detector safety landing

  • Safe landing of detector is the key of planetary exploration, but the success probability of landing is still low, and the study of landing risk is very important in practical engineering. The detector-s structure and landing way were analyzed, and the main influence factors of the safety landing were concluded, then the criterions of safe landing were given. Based on Monte Carlo theory, the planet surface landform and detector landing way were simulated, and the probability of safety landing under blind landing was given by simulation method.Furthermore, consider the detector size and landing area, the sensitivity analysis of the probability of safety landing was carried out, and the results show that the detector size has significant influence on the probability of safety landing.
