specific Embodiment approach 1

[0028] Specific embodiment one: combine 1 to Figure 5Describe this embodiment, the working method of the on-orbit service-oriented rapid rolling target derotation cell sail in this embodiment. The derotation is completed by the cooperation of the parent star and the cell sail. The parent star is the carrier of the laser and is the energy source of the derotation torque. At the same time, as the sending end of the control command, it is the control center of the cell sail, and the cell sail, as the angular momentum derotation device attached to the out-of-control satellite, is the specific executive mechanism for performing the derotation task.

specific Embodiment approach 2

[0029] Specific implementation mode two: combination Figure 1 to Figure 5 Describe this embodiment, the described working method of this embodiment comprises the following steps:

[0030] Step 1, the cell sail is separated from the parent service satellite;

[0031] Step 2. Under the action of the laser propulsion control emitted by the parent star, the cell sail approaches the uncontrolled rolling target;

[0032] Step 3, the cell sail is in contact with the surface of the out-of-control satellite, and the bionic gecko claw on the cell sail is used to generate adhesion to the surface of the out-of-control satellite;

[0033] Step 4. Perform angular momentum racemization on the target based on the cell sail;

[0034] Step 5. The cell sail measures the angular velocity of the out-of-control satellite through the gyroscope. When the angular velocity is less than the preset 10 - 3 When the threshold of rad / s is reached, the cell sail sends instructions to the mother star thr...

specific Embodiment approach 3

[0036] Specific implementation mode three: combination Figure 1 to Figure 5 To illustrate this embodiment, laser propulsion control is adopted in step 2 of this embodiment. The specific principle is: the surface of the cell sail is made of photonic graphene material, and based on the principle that photonic graphene emits electrons outward under light irradiation, the parent star passes through Launch the laser and align it with the graphene light sail structure on the cell sail. The photonic graphene material absorbs energy and ejects electrons outward under the laser irradiation, generating a reactionary thrust. The thrust is changed by changing the intensity of the laser or changing the irradiation of the light sail. The area is controlled, and the direction of the thrust is controlled by changing the position of the light sail surface. Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention relates to a working method of a rapidly rolling target racemic sail for on-orbit service, which relates to a working method of a racemic sail. The invention aims to solve the possible secondary damage caused by the current non-contact derotation scheme to the out-of-control satellite body, as well as the problems of complex structure, low derotation efficiency and low derotation cost. In the present invention, the derotation satellite is composed of a parent star and a cell sail, and the cell sail, as an angular momentum derotation device attached to the out-of-control satellite, is a specific actuator for performing the derotation task, and the parent star is the energy source of the derotation torque , which is also the control center. Before derotation, the cell sail is hidden in the parent star. When working, the cell sail cooperates with the parent star to complete the derotation of the out-of-control satellite through a series of processes such as approaching, adsorption, derotation, and recovery. The invention is suitable for derotation of fast tumbling objects in space.

Description

technical field [0001] The invention relates to a working method of a rapidly rolling target racemic cell sail for on-orbit service, and belongs to the technical field of spacecraft on-orbit service. Background technique [0002] Maintenance and de-orbit processing of out-of-control spacecraft are one of the core tasks of on-orbit service. Most of the out-of-control targets will rotate at a high speed. If they are directly operated, it will bring difficulties to the on-orbit operations such as grasping or docking of the service spacecraft, or cause impact damage to the grasping or docking mechanism, and even cause damage to the service spacecraft. Unsteady. Therefore, it is necessary to eliminate the angular momentum of the rapid rollover of the out-of-control spacecraft before it is repaired or de-orbited. In 2006, a certain type of resource satellite in my country rolled rapidly due to gyroscope stalling and then failed. The first rescue work carried out was to derotate ...
