초록
In this study, the structural stability of a scientific payload installed on a KMSLcubesatellite for combustion experiment mission was investigated by a computational analysis. Ascientific payload was preliminary design based on the design criteria of the pressure vessel, andlinear structure analysis was performed using ANSYS V19.2 to verify the stability. As a result ofthis study, it was indicated that most of the maximum equivalent stress and strain occured in thecenter of the payload optical window. However, the payload designed with a minimum MOS of2.94 has been shown to be structurally stable and robust under the given environmentalconditions. Also the payload optical window can be damaged when the pressure differencebetween the inside and outside of the payload is 5 atmabs.
