摘要： A bumper system for use with a compressor variable vane system comprises a synchronizing ring 46, a bumper 32, a shim 38 for defining a gap between a bumper pad 47 and the bumper 32, a pin 36 for preventing rotation of the bumper 32 relative to the synchronizing ring 46, and a device for fully trapping the shim 38. In a first embodiment (Fig.2), the device for fully trapping the shim 38 comprises a sleeve 34 passing through the synchronizing ring 46. In a second embodiment (Fig. 5), the device for fully trapping the shim 38 comprises a pin 72 which passes through the synchronizing body 46. In a third embodiment (Fig. 6), the device for fully trapping the shim comprises a fastener 30 with a shoulder (82).

摘要： A rotor has a central shaft (31) having a central longitudinal axis. The rotor has a longitudinal stack (32) of a plurality of disks surrounding the shaft (31). An aft hub (70) couples the stack (32) to the shaft (31). The aft hub (70) has a proximal portion (100) and a distal portion (102). The distal portion (102) tapers at a lower characteristic half angle than does the proximal portion (100).

摘要： A gas turbine engine includes a spool (30), a turbine (46) coupled to drive the spool (30) and a propulsor (42) that is coupled to be driven by the turbine (46) through the spool (30). A gear assembly (48) is coupled between the propulsor (42) and the spool (30) such that rotation of the spool (30) drives the propulsor (42) at a different speed than the spool (30). The propulsor (42) includes a hub (76) and a row (72) of propulsor blades (74) that extends from the hub (76). The row (72) includes no more than 16 of the propulsor blades (74).
