Based on the heat release of dedicated electronic boxes, a complete design, manufacturing and integration cycle will be performed for two different mass-efficient heat accumulators using phase change material avoiding overheat of specific electronic boxes on-board a launch vehicle.This includes also dedicated thermal, vibrational and structural analysis to withstand the complete flight mission with mounted electronic boxes.

Digital engineering tools have been used by space thermal analysts for decades, in particular the core modellers, and thermal/radiative kernels used in every space project. However, many parts of the thermal engineering and analysis process are still manual, data exchange is not standardised. Often these parts of the process lie between different main activities, or occur when pure ?thermal analysis? meets adjacent disciplines.
