5.X Low‑Torque Kinetic Harvesting Rings

In addition to the main metre‑class flywheels, the spacecraft employs a set of low‑torque kinetic harvesting rings mounted coaxially around selected drive shafts and structural members. Each ring is supported on low‑friction bearings and coupled to the underlying shaft through a carefully tuned, limited‑torque interface. The design objective is to recover a small but continuous amount of rotational energy without imposing a significant additional mechanical load on the primary drive system.

Under normal operation, the harvesting rings operate in a low‑torque mode, in which the incremental shaft load remains close to the threshold of detectability. In this regime, the rings function as auxiliary generators and micro‑flywheels, supplying background power for housekeeping loads and topping up the super‑capacitor banks. When the spacecraft performs high‑dynamics manoeuvres, such as gravity assists or attitude changes with large reaction wheel activity, the control system can temporarily increase the allowable generator torque, transitioning the rings into a boost mode that extracts substantially more power for a limited duration.

This dual‑mode strategy mirrors the philosophy of kinetic energy recovery systems: it does not attempt to create energy, but to recycle rotational and vibrational energy that would otherwise be dissipated as heat. By carefully limiting the harvesting torque in cruise and only invoking higher torque during dynamically favourable phases, the low‑torque kinetic harvesting rings contribute to the overall energy budget while preserving the stability and efficiency of the primary propulsion and attitude control subsystems.
