RSST math models, block diagrams and predictions

Abstract

The failure rates are listed on reliability worksheets and were adjusted for temperature and stress ratios, and screening reduction factors. The numerical reliability prediction for the RSST two year lunar phase of operation is 0.989. This was determined as shown in the math model from the summation of failure rates of all components in the system, using the negative exponential distribution. The reliability correction factor for the non-operating standby phase of the mission was calculated to be 0.99999.
