1. An integrally bladed rotor portion for a hybrid rotor, the integrally bladed rotor portion comprising:
a rotor disk portion having a peripheral rim configured to mechanically retain an individual rotor blade, wherein the individual rotor blade comprises a plurality of individual rotor blades spaced around the circumference of the rotor disk portion in circumferentially spaced apart sets, each set comprising at least one individual rotor blade; and
a blade portion comprising an integral rotor blade extending outwardly and integrally from the rotor disk portion, the individual rotor blade configured to extend radially outwardly from the rotor disk portion in a blade array with the integral rotor blade, wherein the integral rotor blade comprises a plurality of integral rotor blades spaced around a circumference of the rotor disk portion in circumferentially spaced apart sets, each set comprising one or more integral rotor blades;
wherein each set of the one or more individual rotor blades is disposed circumferentially adjacent and between a pair of adjacent circumferentially spaced apart sets of the integral rotor blades.
