Martin, C. M.

This supplement contains a reevaluation of the thermal analysis of the modular drag disc turbine flow transducer (MDTT). A new analysis was needed because the adaptor blocks for attaching the MDTT to the rake assembly do not allow flow on the sides and ends of the MDTT body. This will raise the MDTT body temperature through the LOCE transient and cause a larger temperature difference between the fairing and ring. Although there are no longer any welds in the end cap, this area still must be evaluated for thermal stresses. The same model in the previous analysis was used here after changing the boundary conditions for the sides and ends of the MDTT. A subroutine was written to give a temperature difference between the ring and fairing. This temperature difference should be used to do a thermal stress analysis. Although this analysis results in a larger temperature difference than the previous analysis, it is expected that the design should be within allowable code requirements since there are no longer any fairing welds. However, this should be verified by the stress analyst.
