SAP IV analysis of a reentering multi-hundred watt heat source assembly. Final report
The results of a three-dimensional stress analysis of a reentering Multi-Hundred Watt Heat Source Assembly are presented. The SAP IV computer program was used for a static analysis of the aeroshell for the maximum stress reentry hypothesized for the NASA Voyager launches. The temperature profile through the aeroshell thickness was applied with given external aerodynamic and inertial loads, and because the axial thermal gradients are unknown at the point of maximum combined stress, a longitudinal temperature gradient which is present at 0.4 seconds later in the reentry is used. Therefore, the results can only be used for order-of-magnitude estimates of the increase in calculated stress, and they indicate an increase on the order of 10 percent over previous SAP IV calculations.
