At a critical moment, Yuan Jie, president of the Shanghai Institute of Aerospace Technology, made a decisive decision and decided to re-upgrade the spacecraft's solar panels to ensure the normal operation of the system electrical of the spaceship. After everyone's efforts, the experiment was finally successful. After the Spring Festival of 2000, the corresponding equipment of each subsystem was delivered to the whole body, and the spacecraft system successively carried out overall tests.
At present, the expansion of satellite solar panels generally relies on memory metal. When the operating temperature changes and reaches a certain temperature, it will automatically expand according to the initially set shape of the solar. the cellular sail panels used are made from shape memory alloy. When the spacecraft is irradiated by the sun after takeoff and the temperatureture reaches a certain value, it automatically unfolds to produce electricity.
