Thermal Gradients
Thermal gradients refer to the variation of temperature in a material or system over a distance. In the context of space and astronautical engineering, thermal gradients are of utmost importance as they can cause significant changes in the properties and behavior of materials and systems. In space, thermal gradients can occur due to the extreme temperature differences between the sun-facing and shadowed sides of a spacecraft or satellite. These gradients can cause thermal stress, which can lead to deformation, cracking, or failure of the material or system. Thermal gradients can also affect the performance of electronic components, such as solar cells and batteries, which are sensitive to temperature changes. Therefore, it is crucial to design spacecraft and satellites with materials and systems that can withstand thermal gradients and to implement thermal control systems to regulate temperature and minimize thermal stress.
