Resumo

In this work, the use of a Thermally Integrated Structural Sandwich Core (TISSC), a new kind of space vehicle thermal protection is proposed, replacing the conventional cork layer used as a TPS (Thermal Protection System). The TISSC is applied to the SARA sub-orbital platform, which is being developed by IAE/CTA for micro-gravity research. The advantages of using such a structure are its lightweight and the same insulation as load bearing capabilities, low maintenance, and low life-cycle cost. A specific layout for this system is studied via computational simulation, and the thermal performance with diverse materials is evaluated. Results show the presence of hot spots in the internal wall, where the links between the external and internal walls are placed.
