Abstract

The application discloses a spacecraft of double-configuration atmosphere sail based on cross-section formation, which comprises front and rear atmosphere sail units (1, 6) and atmosphere sail units (2, 3, 4, 5) installed between the front and rear atmosphere sail units; a center joint (9) is arranged in the middle of the double-configuration atmosphere sail spacecraft; a right end folding shaft assembly (7) and a left end folding shaft assembly (8) are arranged at two ends of the center joint (9) respectively. The frame of the double-configuration atmosphere sail spacecraft is a rectangular frame unit formed by support rods and angle connectors. In order to solve the problems of large volume, large mass and large fuel consumption for stable control of a traditional spacecraft attitude and orbit control system, the double-configuration atmosphere sail spacecraft based on cross-section formation does not need to consume fuel, and only relies on atmospheric resistance to realize attitude and formation configuration stability, so that the light weight of the spacecraft is realized.

Description

Technical Field

[0001] This invention relates to a low-orbit sail spacecraft, specifically to a spacecraft based on a cross-formation dual-configuration atmospheric sail, suitable for space missions such as Earth imaging, electronic reconnaissance, and controlled deorbiting. Background Technology

[0002] Satellite swarming is a common method used in the aerospace field to enhance mission efficiency, and it is currently developing towards higher precision and lower cost. Multiple satellites in swarms can significantly improve the efficiency of space missions, enabling them to perform tasks that are impossible for a single satellite, such as distributed InSAR swarming, 3D imaging, and electronic reconnaissance of Earth. On the other hand, low-Earth orbit (LEO) satellites have advantages in miniaturization, low power consumption, and low cost, allowing them to achieve higher imaging resolution at a lower cost. Furthermore, as the orbital altitude of LEO satellites decreases from 450km to 250km, the aerodynamic forces they experience increase by two orders of magnitude, making aerodynamic forces and moments crucial factors to consider.

[0003] In existing engineering missions, it is often necessary to constantly adjust the formation configuration to achieve imaging of regions across all latitudes. Achieving a stable transverse formation configuration to simulate binocular vision by having satellites fly side-by-side could significantly improve the quality of Earth imaging. However, maintaining the relative positions of multiple satellites in a formation remains an engineering challenge: forcibly achieving a stable configuration using attitude control engines consumes a large amount of fuel; using the space shuttle's thin rods for support limits the relative baseline length; simply tethering satellites cannot achieve a constant vertical component of the relative baseline; and using momentum wheels, torque generators, and other equipment increases the spacecraft's mass and power consumption.

[0004] Currently, the combination of tethered satellites and sail-based spacecraft holds promise for achieving fuel-free orbital maintenance. However, due to the similar magnitudes of solar radiation pressure perturbations and atmospheric drag perturbations in low Earth orbit, maintaining stable control of solar sail spacecraft is relatively difficult and unsuitable for long-term Earth imaging. Summary of the Invention

[0005] To address the technical problems of traditional spacecraft attitude and orbit control systems, such as large size, large mass, and the need for large amounts of fuel for stable control, this invention provides a lightweight spacecraft based on a cross-shaped formation dual-configuration atmospheric sail that can achieve attitude and formation stability without consuming fuel, relying solely on atmospheric drag.

[0006] This invention relates to a spacecraft based on a transverse formation dual-configuration atmospheric sail, comprising a front atmospheric sail unit (1), a rear atmospheric sail unit (6), and various atmospheric sail units (2, 3, 4, 5) installed between the front atmospheric sail unit (1) and the rear atmospheric sail unit (6); a central joint (9) is provided in the middle of the dual-configuration atmospheric sail spacecraft; a right-end folding shaft assembly (7) and a left-end folding shaft assembly (8) are respectively provided at both ends of the central joint (9). The frame of the dual-configuration atmospheric sail spacecraft is a rectangular frame unit formed by support rods and corner connectors. The support rods are made of carbon fiber tubes. The corner connectors are integrally molded structural parts made of nylon carbon fiber by 3D printing.

[0007] In this invention, the number of atmospheric sail units located between the front atmospheric sail unit (1) and the rear atmospheric sail unit (6) can be increased or decreased according to the functional requirements of the dual-configuration atmospheric sail spacecraft.

[0008] In this invention, the dual-configuration atmospheric sail spacecraft features a distributed atmospheric sail and propulsion structure. By rotating and twisting the sail surface, the drag generated when atmospheric molecules at a certain speed pass over the sail surface is decomposed into control forces and control torques required to control the attitude, thereby achieving control of the spacecraft.

[0009] Compared with the prior art, the advantages of the present invention based on the transverse formation dual-configuration atmospheric sail are:

[0010] ① This invention, through the design of the atmospheric sail distribution and drive structure, enables the spacecraft to control its attitude through autonomous control of the sail surface, solving the attitude-orbit coupling problem of ordinary sail-type spacecraft and reducing the control difficulty.

[0011] ② This invention makes reasonable use of the aerodynamic drag of low-Earth orbit spacecraft, turning it into a beneficial control force. At the same time, the satellite does not need to carry fuel or power to maintain attitude, orbit, and formation stability.

[0012] ③ This invention enables rapid configuration changes for satellite formations. Through the aerodynamic control forces provided by the distributed atmospheric sail structure, free attitude and orbit control can be achieved, thereby allowing for rapid changes in the configuration of the satellite formations.

[0013] ④ This invention introduces a dual configuration of continuous and discrete sail surfaces, which improves on-orbit reliability.

[0014] ⑤ This invention reduces the development cost and shortens the development cycle of formation satellites. The designed sail-shaped spacecraft reduces the need for power supplies, telemetry and remote control equipment, traditional momentum wheels, etc., which greatly reduces development costs and the development cycle spent on ground testing.

[0015] ⑥ This invention can be applied to enhance space-based telemetry and control systems and is expected to become a new platform for the next generation of remote sensing satellites. Attached Figure Description

[0181] Horizontal and Torsional Rotation of Atmospheric Sails

[0182] See in this invention Figure 7 As shown, the horizontal rotation of the atmospheric sail means that the right-end servo motor and the left-end servo motor in the atmospheric sail unit (1-6) drive in the same direction, so that the flexible sail in the atmospheric sail unit moves in the same direction.

[0183] See in this invention Figure 8 As shown, the twisting of the atmospheric sail surface refers to the fact that the right-end servo motor and the left-end servo motor in the atmospheric sail unit (2-5) have different driving directions, causing the two ends of the flexible sail in the atmospheric sail unit to move in different directions.
