Description

Technical field

[0001] The invention belongs to a solar battery sail panel unfolding mechanism in the field of civil spaceflight. Background technique

[0002] The solar panel deployment mechanism is very important in the aerospace field. Existing unfolding mechanisms generally belong to rotary joints or hinge mechanisms, and the structure tends to be complex and needs to be driven by a motor. A problem with one of the components will affect the work of the entire mechanism. The space industry has developed to the present. According to statistics, there are about 26 cases of solar panel failures, including about 11 cases of mechanical deployment failures, including Fleet Communications Satellite 5, Alnwick BF1, April Test Communications Satellite, Indian Satellite 1A, and Indian Satellite 1B. , Arab Satellite 1, TV-Sat TV live satellite, Soyuz 1 spacecraft, US weather satellite Nimbus 1, US weather satellite GOES210, TIP navigation satellite, etc. Mechanical failures of th...
