| Abstract: | This paper introduces and analyzes Monte-Carlo(MC) technique for thermal model correction of spacecraft. An inverse problem of spacecraft model is developed,which is solved with MC scenario.A practical example is given to correct stochastic parameters on MC method with ThermalDesktop+SindaFluint software. The computational results show that the MC scenario is effective for correcting parameters and demands less manpower. The results can be used to instruct the follow-on engineering design. |
