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

摘要

A thermal disconnect assembly (12) for an integrated drive generator includes an input shaft (14), an output shaft (30), a eutectic solder (36), and a disconnect clutch (38). The input shaft (14) is driven by an external mechanical source. The output shaft (30) is coupled to the input shaft (14) through a disconnect clutch (38) in a coupled state, is driven by the input shaft (14) and rotates with the input shaft (14) in the coupled state. The eutectic solder (36) is configured to hold the output shaft (30) in the coupled state and melt upon reaching a threshold temperature. The disconnect clutch (38) is configured to urge the output shaft (30) toward a decoupled state upon melting of the eutectic solder (36) such that the output shaft (30) does not rotate with the input shaft (14) in the decoupled state.
