Retractable Mechanism
Retractable Mechanism refers to a system that allows a component or structure to be extended or retracted as needed. In the context of space and astronautical engineering, retractable mechanisms are commonly used in spacecraft and satellites to deploy solar arrays, antennas, booms, and other instruments. These mechanisms are designed to withstand the harsh conditions of space, including extreme temperatures, radiation, and vacuum. They are often operated by motors, springs, or pyrotechnics, and must be carefully tested and validated before launch to ensure reliable performance. Retractable mechanisms are critical to the success of many space missions, as they enable spacecraft to gather data, communicate with Earth, and generate power. They also help to minimize the size and weight of spacecraft during launch, which can reduce costs and increase mission flexibility.
