THERMAL DISCONNECT ASSEMBLY WITH FLIGHT CONTROL PERMANENT MAGNET GENERATOR FOR INTEGRATED DRIVE GENERATOR

摘要

A thermal disconnect assembly for an integrated drive generator includes an input shaft, an output shaft, a eutectic solder, and a disconnect clutch. The input shaft is driven by an external mechanical source. The output shaft is coupled to the input shaft through a disconnect clutch in a coupled state, is driven by the input shaft and rotates with the input shaft in the coupled state. The eutectic solder is configured to hold the output shaft in the coupled state and melt upon reaching a threshold temperature. The disconnect clutch is configured to urge the output shaft toward a decoupled state upon melting of the eutectic solder such that the output shaft does not rotate with the input shaft in the decoupled state.
