Description

Technical Field

[0001] The utility model belongs to the technical field of spacecraft, and in particular relates to a spacecraft with a solar sail propulsion function. Background Art

[0002] A solar sail spacecraft is a spacecraft that uses the light pressure of sunlight to navigate in space. Since this thrust is very small, the spacecraft cannot take off from the ground. However, in space where there is no air resistance, this small thrust can still provide acceleration for a solar sail with sufficient sail area. A solar sail spacecraft relies on sunlight to roam in space, does not carry fuel and is constantly accelerating.

[0003] However, during the operation of existing solar sail-propelled spacecraft, due to the problem of operating angle, it is impossible to timely adjust the illumination area that the solar sail can receive according to the operating trajectory, resulting in low efficiency of the solar sail, and the operating speed does not reach the ideal effect, which increases the working operation time. Secondly, when operating outside the atmosphere, the existing solar sail-propelled spacecraft will cause a large amount of electromagnetic radiation on the surface of the solar sail due to long-term sunlight exposure, which in turn increases the metal shielding layer on the radio wave propagation path, affecting the transmission of the radio wave signal, and further affecting the operating speed of the solar sail spacecraft. Therefore, there is room for improvement. Utility Model Content
