<p>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).</p> |
