Rotary machines including a hybrid rotor with an integrally bladed rotor portion

A hybrid rotor comprising:

• an integrally bladed rotor portion comprising a rotor disk portion having a peripheral rim and a blade portion comprising a plurality of integral rotor blades extending outwardly and integrally from the rotor disk portion;
• and
• a plurality of individual rotor blades extending outwardly from the rotor disk portion in a blade array with the plurality of integral rotor blades;
• wherein the plurality of integral rotor blades are spaced around a circumference of the rotor disk portion in circumferentially spaced apart sets, each set comprising one or more integral rotor blades and the plurality of individual rotor blades are spaced around the circumference of the rotor disk portion in circumferentially spaced apart sets of one or more individual 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 integral rotor blades.

A rotary machine comprising:

• an integral rotary body having a plurality of integral blades extending outwardly and integrally from a peripheral rim thereof;
• and
• a plurality of individual blades extending outwardly from the peripheral rim and mechanically retained by a mechanical retention slot in the peripheral rim;
• wherein each integral blade of the plurality of integral blades is circumferentially disposed between adjacent individual blades of the plurality of individual blades and wherein each individual blade of the plurality of individual blades is circumferentially disposed between adjacent integral blades of the plurality of integral blades.
