摘要： A dual drive, dual clutch accessory drive system for an aircraft including a first input shaft (86) connected to a first pressure spool (48) of a turbine engine. The first input shaft rotates at a first speed. A second input shaft (88) is connected to a second spool (50) of the turbine engine that is distinct from the first spool. The second input shaft rotates at a second speed. An output shaft (90) operatively connected to an aircraft accessory. A first drive path selectively operatively connects the first input shaft with the output shaft. The first drive path (94) includes a first clutch (60). The first drive path being operable to rotate the output shaft at the first speed. A second drive path (96) operatively connects the second input shaft with the output shaft. The second drive path includes a second clutch (110). The second drive path is operable to rotate the output shaft at the second speed.

摘要： An engine system (10) includes a turbine engine (14) having a high pressure spool (28) and a low pressure spool (26). A transmission includes an input shaft (31) connected to one of the high pressure spool (28) and the low pressure spool (26), and an output shaft (33). A clutch (40) is arranged between the input shaft (31) and the output shaft (33). A generator (36) is connected to the output shaft (33). A clutch controller (42) activates the clutch (40) when one of the high pressure spool (28) and the low pressure spool (26), and the generator (36) are operating at a selected speed range.

摘要： A turbomachine dual spool transmission system (700) can include a direct drive assembly (701) configured to selectively allow bypassing of a dual spool differential combination output (107) to allow selective direct engagement of a low pressure spool (LS) to directly drive a rotational member (703; 109) or to be directly driven by the rotational member. The system can include the dual spool differential. The dual spool differential can include a gear assembly configured to combine a low pressure spool input and a high pressure spool input into a combination output to provide an output speed range smaller than a low pressure speed range alone.
