6 Frequently Asked Questions about “Introduction to the spacecraft solar cell wing”
How does a flexible solar wing work?
The flexible solar wing proposed in this study employs a scissor-like mechanism to deploy and support a large cell array. It is stowed in the payload bay during the launch phase. Once in orbit, the spacecraft will deploy and lock the structure to maintain shape.
Why do spacecraft use solar cell arrays?
The availability of sunlight has encouraged the development of solar cell arrays, Simplicity, relatively modest cost, and high reliability have caused this system to be chosen to supply sus-• tained electrical power for almost all unmanned spacecraft. . The performance of a spacecraft solar cell array depends on many parameters.
What type of solar wing does the ISS use?
For instance, the International Space Station (ISS) uses a Folding Articulated Square Truss (FAST) for its solar wing component, the EOS-AM1 employs a 26-panel flexible solar array, and the CSS utilizes a flexible solar array wing (FSAW) comprising a truss and two flexible solar cell wings [13, 14].
Does a flexible solar wing have an in-plane dynamic response?
Additionally, in-plane dynamic patterns were summarized, indicating that the diameter of the hinge pin is more sensitive than the width of the hinge piece and thus has a more significant effect on the system dynamics. These studies enhance our understanding of the in-plane dynamic response of the flexible solar wing.
Why are rigid solar wings not suitable for spacecraft?
Currently, rigid solar wings [4, 5], which suffer from disadvantages such as large envelope size, high overall mass, and low specific power, cannot meet the increasing power generation requirements because enlarging the area of rigid panels inevitably limits spacecraft mass and envelope space [7, 8].
What is the deployment sequence of flexible solar wings in orbit?
The deployment sequence of flexible solar wings in orbit is divided into four phases, as shown in Fig. 1b: (a) the stowed phase, (b) the deploying phase, (c) the deployed phase, and (d) the tensed phase. The scissor-like mechanism is motor-driven for active deployment.
