Thermal Properties
Thermal properties refer to the characteristics of materials that determine their ability to conduct, store, and transfer heat. In the context of space and astronautical engineering, thermal properties are crucial for designing spacecraft and equipment that can withstand extreme temperatures and thermal environments. These properties include thermal conductivity, specific heat capacity, thermal expansion coefficient, and emissivity. Thermal conductivity is the ability of a material to conduct heat, while specific heat capacity is the amount of heat required to raise the temperature of a unit mass of the material by one degree Celsius. Thermal expansion coefficient is the rate at which a material expands or contracts with changes in temperature, and emissivity is the ability of a material to emit thermal radiation. Understanding and controlling these thermal properties is essential for ensuring the safety and functionality of spacecraft and equipment in the harsh conditions of space.
