Thermal Expansion Coefficient
Thermal Expansion Coefficient is the ratio of the change in length or volume of a material to the original length or volume, per degree of temperature change. In space and astronautical engineering, thermal expansion coefficient is an important property of materials used in spacecraft and satellites. The coefficient determines how much a material will expand or contract under different temperature conditions. This is important because spacecraft and satellites are exposed to extreme temperature changes in space, and the materials used in their construction must be able to withstand these changes without breaking or deforming. The thermal expansion coefficient is also used in the design of thermal control systems, which regulate the temperature of spacecraft and satellites by controlling the amount of heat that is absorbed or radiated by the spacecraft or satellite.
