ABSTRACT:
This invention provides for heating a brake assembly electrically to prevent it from freezing. More specifically this invention provides for heating electrically an aircraft multi-disk brake assembly.
An electric resistance heating element 12 is adapted to form a heater 10 to provide heating to a brake stack 44. Heat may be transferred either directly to the brake stack 44 or indirectly by first heating a member of the brake assembly 36. This member in turn transfers heat to the brake stack.
The heater 10 may be formed to fit within the cavity formed by a torque tube 26 wherein the heater abuts a substantial portion of the torque tube 26.
Signals from a thermocouple may be used for activation and deactivation of the heater 10.
