This study analyzes the effect of extreme temperatures on the spacecraft's skin during atmospheric re-entry using the Computational Fluid Dynamics (CFD) method and ANSYS Student 2025 R2 software. The analysis results showed that each material has a varying thermal response. Aluminum alloy AL-7079 exhibits non-uniform heat distribution, potentially leading to thermal stress and crackin6. Cast Carbon Steel is susceptible to material fatigue at extreme temperatures. Magnesium alloy AZ-31 lacks adequate resistance to extreme temperatures, absorbing excessive heat. Of the four materials tested, Titanium TI-55 demonstrated the most superior thermal performance. This material is able to absorb and dissipate heat evenly, preventing hot spots, and maintaining the structural integrity of the vehicle under extreme conditions. This study concludes that Titanium TI-55 is the most effective choice to address thermal challenges in spacecraft.
