Description

technical field

[0001] The invention relates to a solar battery array of a spacecraft, in particular to an expandable solar battery array and a pressing and releasing mechanism thereof. Background technique

[0002] With the improvement of our country's national defense needs and the vigorous development of civil aerospace, the demand for on-orbit energy power of spacecraft is increasing, and a larger area is required for solar arrays, the core power supply equipment of spacecraft. However, limited to the envelope of the fairing of the launch vehicle, the large-area solar cell array needs to adopt a deployable configuration design to achieve the effective compression and overload of the launching section in the folded state, and reliable release after orbiting to implement deployment and lock to maintain the shape. the goal of. Traditional deployable solar cell arrays and their compression and release mechanisms include body-mounted, single-panel, multi-panel, and other con...
