A fusible plug in landing gears is a safety device designed to prevent tire explosions due to overheating. It is a small, heat-sensitive plug embedded in the wheel assembly, usually within the tire rim.
Function: • Aircraft brakes generate a lot of heat during landing, especially in high-speed or rejected takeoff scenarios. • If the temperature exceeds a critical limit (usually around 177–204°C or 350–400°F), the fusible plug melts. • This allows the tire to deflate gradually rather than bursting violently, which could cause significant damage or injury.
Why is it important? • Prevents catastrophic tire bursts on the ground. • Reduces stress on landing gear components. • Enhances overall aircraft safety.
Fusible plugs are commonly found in large commercial and military aircraft where braking loads are high.
