DUAL-RING SUPERCONDUCTING ARTIFICIAL-GRAVITY HABITAT
SPACE SYSTEMS: HABITATION & SHIELDING · ACCELERON AEROSPACE JOURNAL VOL. 6 NO. 2 (2026) PP. 1–48ABSTRACT
Long-duration human habitation beyond Earth's magnetosphere requires artificial gravity to prevent the progressive musculoskeletal, cardiovascular, and neurovestibular deterioration observed in sustained microgravity exposure. Existing artificial gravity concepts: tethered systems, single-ring centrifuges, and rotating drums: each exhibit fundamental limitations in gyroscopic coupling, structural complexity, or mission scalability.
This paper presents the Griffiths Dual-Ring Superconducting Artificial-Gravity Habitat Architecture, which addresses these limitations through three integrated innovations: counter-rotation of two concentric rings to achieve zero net angular momentum; superconducting magnetic levitation providing contactless bearing support and structural rigidity without mechanical wear; and modular architecture integrating with the complete Griffiths Canon of propulsion, governance, EVA, and defence systems.
The outer ring (100 m diameter) provides 0.8 g at 3.78 RPM; the inner ring (75 m diameter) provides 0.6 g for laboratory operations. Superconducting HTS coils operating at 20–40 K provide electromagnetic bearing functionality with field stability maintained at ±0.01 T through closed-loop flux feedback. Coriolis acceleration at walking speed (1 m/s) is 0.79 m/s² (8.1% of local gravity), within published adaptation limits. The gravity gradient across a 1.8 m crew height is 3.6%, negligible relative to physiological thresholds.

CONCLUSIONS
The Dual-Ring Habitat architecture delivers 0.8 g at the outer ring floor and 0.6 g at the inner ring laboratory floor at 3.78 RPM, within the human adaptation envelope. Zero net angular momentum through counter-rotation eliminates gyroscopic coupling with vehicle attitude control. Superconducting magnetic levitation eliminates mechanical bearing wear, providing a maintenance-free bearing system rated for multi-year deep-space operation.
The architecture integrates cleanly within the Griffiths Canon, with defined structural, power, thermal, and governance interfaces to GRFF, GNMT, MSH, NGLS, and DIGSP. The GRFF four-layer defence envelope mounts directly to the outer ring structure, providing habitat survivability in the micrometeoroid and radiation environments of deep space.
Priority future work includes long-duration physiological validation at 3.78 RPM, HTS coil space qualification testing, and a sub-scale maglev bearing demonstrator.
