5mm Solar Array
5mm Ultrathin and Lightweight Rigid Solar Array is applied to small satellite platform as the structure support for the solar cell. It has the following characteristics: lightweight, low shock, high reliability, expansibility, etc. At present, it has passed qualification tests. With the wide application and increasing quantity of small satellite, 5mm Ultrathin and Lightweight Rigid Solar Array has wide application prospects.
5mm Ultrathin and Lightweight Rigid Solar Array consists of 5mm ultrathin composite material panels, Micro-type hinges and SMA hold-down and release mechanisms.
5mm Ultra-thin composite material panel is the first time to be applied in solar array in China and attains the domestic leading level. Micro-type hinge has the characteristics of light-weight (43g), high stiffness and high reliability, etc. SMA hold-down and release mechanism has solved the problem of high shock in traditional space pyrotechnics devices. It has many good qualities such as pollution-free, reuse ability and comes up to the advanced domestic standards. The main properties of 5mm Ultrathin and Lightweight Rigid Solar Array are shown below.
