摘要

A fan rotor ring for an air cycle machine includes a ring body that defines a main bore having a main bore diameter and central axis. An annular flange extends axially from the ring body over a length and defines a fan ring bore having a fan ring bore inner diameter. A ratio of the fan ring bore inner diameter to the length of the annular flange is 1.63-1.69.
