<p>An integrally bladed disk (24A, 24B, 24C) includes a rim (30) and blades (34a, 34b). The blades are circumferentially spaced and extend integrally outward from the rim to define a flow path (50a, 50b, 50c) therebetween. The periphery of the rim forms a flow surface (36) and includes a trench (42a, 42b, 42c) that is disposed adjacent the blades.</p> |
