Publication number: 20240059431Abstract: A solar array structure for a spacecraft is based on a modular approach, allowing for arrays to be designed, and designed to be modified, and manufactured in reduced time and with reduced cost. The embodiments for the solar array are formed of multiple copies of a “bay” of a multiple strings of solar array cells mounted on semi-rigid face-sheet structural elements. The bays are then placed into frame structures made of tubes connected by nodes to provide an easily scalable, configurable, and producible solar array wing structure. This allows for rapid turnaround of program specific designs and proposal iterations that is quickly adaptable to new/future PhotoVoltaic (PV) technologies and that can create uniquely shaped (i.e., not rectangular) arrays, allowing for mass production with simple mass producible building blocks.Type: ApplicationFiled: November 3, 2023Publication date: February 22, 2024Applicant: Maxar Space LLCInventors: Harry A. Yates, Tom Hsieh, Ryan Bieniek, Ben Kwong, Robert Szombathy, Martinus Meerman, Frederick Oey, Peter Amnuaypayoat, Alan J. Szeto, Richard B. Warnock
