When it comes to coil spring, most people first think of the tape measure that is common in life. A large slap in the palm of your hand, through the role of coil spring to achieve retractable. However, do not underestimate this common small coil spring, is such a seemingly humble small parts are interpreted ”big as “. In the implementation of the Shenzhou 8 spacecraft and Tiangong 1 docking mission, it is this volume of about 7cm diameter coil spring, solar panels have become the fold of each layer can be folded exactly the exact time the key. ”If the solar panels can not be accurately deployed, then the spacecraft will not be able to accept sufficient new energy
