Claim:
1. A thermal disconnect assembly for an integrated drive generator, the thermal disconnect assembly comprising: an input shaft driven by an external mechanical source; an output shaft coupled to the input shaft through a disconnect clutch in a coupled state, wherein the output shaft is driven by the input shaft and rotates with the input shaft in the coupled state; a eutectic solder configured to hold the output shaft in the coupled state, wherein the eutectic solder is configured to melt upon reaching a threshold temperature; and a flight control permanent magnet generator operably coupled to rotate with the output shaft, wherein the flight control generator is located annularly about the input shaft and is coupled to the input shaft through a disconnect bearing, and wherein the disconnect bearing comprises: wherein the disconnect clutch is configured to urge the output shaft toward a decoupled state upon melting of the eutectic solder, and wherein the output shaft does not rotate with the input shaft in the decoupled state.
