A deep-space solar sail spacecraft driven by sunlight pressure

Abstract

The invention discloses a deep space solar sail spacecraft driven by utilizing sunlight pressure. The deep space solar sail spacecraft driven by utilizing the sunlight pressure comprises a support frame, four support arms, four isosceles right triangle sail covers, a first solar cell, an etching antenna, two sliders and four roll axis stabilization mechanisms. The deep space solar sail spacecraft disclosed by the invention has the advantages that an open support packaging structure and a gird are adopted, and an outer packaging structure of a traditional satellite is removed, so that the mass of the solar sail spacecraft is reduced; inflation systems and air storage structures in traditional inflatable deployment support arms can be removed due to the fact that the self-deployment support arms are adopted, so that the mass of the solar sail spacecraft is reduced; by applying the wireless communication technology, the use of a communication line is reduced, so that communication and data transmission can be performed respectively by all parts of the large-area solar sail spacecraft, and the mass of the solar sail spacecraft is reduced; the sliders and the roll axis stabilization mechanisms are used for attitude control, and thus, the triaxial attitude control of the solar sail spacecraft can be realized; compared with spin stabilization attitude control, the triaxial attitude control can be used for executing broader tasks.

Description

technical field [0001] The invention relates to a sail-shaped spacecraft, in particular to a solar sail spacecraft which utilizes sunlight pressure as a driving force and has the ability to carry out deep space exploration. Background technique [0002] Sail-shaped probes driven by solar light pressure, also known as solar sail spacecraft, are spacecraft that use solar light pressure for space navigation. In an ideal situation, the solar sail spacecraft does not need any fuel, and it can obtain continuous thrust from the inexhaustible sunlight to fly into space. As long as the shape and inclination are appropriate, the solar sail spacecraft can fly in any direction including the light source, especially in deep space exploration, which has great advantages. [0003] Photons hit the surface of the solar sail and are completely reflected back, producing a reaction force on the solar sail to push the solar sail to space travel, which is called light pressure drive. In order f...

Problems solved by technology

However, the existing spinning solar sails are not suitable for large-scale deployment. Therefore, for deep space exploration missions, it is urgent to study a support arm form that can be deployed on orbit, has a large area-to-mass ratio, and meets the needs of deep space exploration missions. solar sail spacecraft
