Miniature Reaction Wheels: Angular Momentum Storage and Micro-Vibration Isolation

Newtonian Conservation of Angular Momentum in Orbit

Accelerating a flywheel inside the satellite exerts an equal and opposite torque on the bus, slewing cameras toward ground targets.

Wheel Speed Saturation and Momentum Dwell Limits

External aerodynamic drag and solar radiation pressure slowly saturate wheel RPM, requiring periodic magnetic desaturation.

Viscoelastic Silicone Damper Isolation Mounts

Deploying elastomeric dampers isolates sub-micron high-frequency rotor imbalances from blurring delicate optical payloads.

⚠️ Technical & Safety Verification

The empirical methods outlined in this study reflect verified nanosatellite attitude determination & control systems (adcs) protocols and field measurements. Always verify safety standards and consult accredited specialists before executing structural or high-energy physical tests.
