INSERTS FOR SLOTTED INTEGRALLY BLADED ROTOR

Integrally bladed rotors (IBRs) are described. The IBRs include a central hub (306;506;606), an outer rim (302;502;602) defining an outer circumference of the central hub, the outer rim defining a plurality of platforms, a plurality of circumferentially distributed blades (304;504;604), wherein a bl...

Zusammenfassung:	Integrally bladed rotors (IBRs) are described. The IBRs include a central hub (306;506;606), an outer rim (302;502;602) defining an outer circumference of the central hub, the outer rim defining a plurality of platforms, a plurality of circumferentially distributed blades (304;504;604), wherein a blade extends from each of the plurality of platforms, a rotor slot (308;508) arranged between two adjacent blades, wherein the rotor slot is defined by a cut within the outer rim, and a rotor slot insert (520;612) installed within the rotor slot, the rotor slot insert sized and shaped to fit within the rotor slot and prevent air leakage from a first side (608) of the central hub to a second side (610) of the central hub through the rotor slot during operation of the integrally bladed rotor.
