Study Notes
Fusible Plugs
- Fusible plugs are safety devices installed in aircraft tires.
- They are designed to melt and release tire pressure when the wheel temperature exceeds a predetermined level, preventing tire explosions.
Aircraft Wheel Bearings
- All aircraft wheels utilize tapered roller bearings.
- These bearings are specifically designed to withstand high loads and rotational speeds.
- To protect against contamination, they are sealed and shielded by a spacer tube.
