“…Flux-pinned interfaces leverage the dynamics of magnetic flux pinning to control the relative orientation and position of close-proximity spacecraft without mechanical contact. These unique traits make flux-pinned interfaces a technology candidate for applications such as spacecraft capture and docking 1,2 , assembly of modular systems 3,4 , formation flying [5][6][7] , kinematic mechanisms 8,9 , and station-keeping 10,11 . However, for this technology to be mature enough for spaceflight applications, its physics must be represented in a high-fidelity predictive dynamics model that can inform design trade and analyses.…”

Flux-pinned interfaces maintain a passively stable equilibrium between two spacecraft in close-proximity.Although flux-pinning physics has been studied from a materials-science perspective and at the systems level, the sensitivities and implications of system-level designs on the dynamics need to be better understood, especially in interfaces with multiple magnets and superconductors. These interfaces have highly nonlinear, coupled dynamics that are influenced by physical parameters including strength of magnetic field sources, field-cooled position, and superconductor geometry.Kordyuk's frozen image model successfully approximates the characteristics of flux pinning dynamics but could provide more precise state prediction with the addition of these physical parameter refinements. This paper addresses that gap by offering parametric terms to improve the dynamics model, which may better simulate the behavior of a multiple-magnetmultiple-superconductor interface. The sensitivity of the general flux-pinned dynamics model is studied by varying the physical parameters and simulating the systems level dynamics. This work represents a critical step in the development of a model suited to spacecraft performance verification.

“…F LUX-PINNED interaction between high T c superconductors and an applied magnetic field provides a new, nocontact interface approach that can be used in the docking and assembling process of space module systems [1]. Generally, there are two feasible methods that can be used to magnetize a bulk superconductor before it interacts with a magnet: pulse field magnetization (PFM) and field-cooled magnetization (FCM).…”

Pulse field magnetization (PFM) is viewed as an appropriate method to provide a strong trapped field in a superconductor. However, a large amount of heat is generated because of dynamic motion of magnetic flux during PFM, which will affect the trapped field and the corresponding magnetic force properties. In this paper, an electromagnetic simulation of the PFM coupling with heat transfer is conducted. The time evolution and the spatial distribution of the temperature and induced current in the superconductor are studied. The magnetic force between the magnetized bulk and an electromagnet is also simulated to show the influence of the PFM on the application of the bulk into a superconducting interface module. The simulation suggests that the initial temperature of the bulk has an important influence on the current density and heat distribution in the magnetized bulk. In addition, with the objective of a stable mechanism for docking and self-assembly of space module systems, the effect of pulse field magnitude and the temperature fluctuation on the interaction force characteristics are also analyzed and discussed.

“…Recently, researchers in Cornell University studied the extended application of the superconducting interaction in station-keeping, formation and reconfiguration of modular space systems [4]. However, because the operating process happened in orbit, an unstable interfacing process was observed in a low gravity fight experiment [5], and difficulties in the magnetization and flux trapping of bulk superconductors were reported. Our experimental work [6] also showed that the interface force was seriously affected by magnetization conditions of the HTS.…”

Flux-pinned interaction between high temperature superconductor and applied field provides a new, nocontacting interfacing approach to positive docking and assembling of space module systems. A superconducting interface module configuration is presented in this paper, which consists of a bulk superconductor, an actuation magnet, and an interfacing magnet. The induced current and magnetic flux density in the superconducting interface module are simulated based on H formulation, and electromagnetic properties of the module subject to different magnetization conditions are demonstrated. Primary experiments are also carried out to understand the magnetization and quasi-static force properties. The measured data partly agree with the simulated results, indicating the valid usage of the H formulation method in the modeling of the superconducting interface module.
