How long does it typically take for the maximum temperature to reach the wheel brake assembly?

The maximum temperature of the wheel brake assembly typically takes about 15 minutes to be fully reached after the brakes have been applied. This duration accounts for the time required for the friction generated from braking to convert kinetic energy into heat. The braking process generates heat through friction between the brake pads and the rotors, and it doesn't reach equilibrium immediately.

This time frame is crucial for understanding the thermal characteristics of brake systems, especially in aviation, where managing brake temperatures is vital for performance and safety. Knowledge of how quickly brakes heat up helps in determining safe operation limits and planning for subsequent use of brakes after landing or during intense braking scenarios.

Less time, like the shorter options, would imply that brakes heat up too quickly, potentially underestimating the thermal inertia of the braking system. Whereas longer durations may suggest a very slow heat build-up, which doesn't align with the rapid thermal dynamics involved in aviation braking systems.
