Abstract
The ablative bushing (40, 140, 240) is disposed between a torque tube pedestal (18) and an axle (30) of an aircraft. The ablative bushing (40, 140) encircles an axle bushing (26) located around the axle (30), so as to be disposed between the torque tube pedestal (18) and axle bushing (26). The ablative bushing (240) may also be located between a torque tube pedestal flange (114) and an axle flange (35). The ablative bushing (40, 140, 240) ablates at a predetermined temperature in order to introduce an air gap between the torque tube pedestal (18) and axle (30) to prevent excessive heat flow to the axle (30) during a rejected take-off stop.
