A fan rotor for an aircraft environmental control system ram fan is provided. The fan rotor includes central body defining a central axis and a radius having a first radial distance that is defined as a distance from the central axis to an edge of the central body. A plurality of fan blades extend radially from the edge of the central body to a second radial distance, the second radial distance defined as a distance from the central axis to a tip of the fan blades. A shroud extends circumferentially between and connecting each of the plurality of fan blades. The shroud is located at a radial distance from the central axis that is greater than the first radial distance and includes one or more tuning features configured to mistune a vibration of the fan rotor during operation.
