Abstract
A blisk includes a disk having a rim. A row of blades extends outwardly from the rib in a unitary construction. The blades are spaced apart in the disk rim to define fluted inner flowpath channels extending axially between the blades to bound corresponding flow passages therebetween.
Claims20
A blisk comprising:
- a disk including a rim;
- a row of blades extending radially outwardly from said rim in a unitary construction therewith to define corresponding flow passages therebetween;
- and
- said disk rim includes fluted inner flowpath channels extending axially between said blades for bounding said passages, with each of said fluted channels extending circumferentially between adjacent blades and having a circumferentially concave contour therebetween.

A compressor blisk comprising:
- a disk including a rim having axially opposite forward and aft ends, and increasing in diameter therebetween;
- a row of compressor blades extending radially outwardly from said rim in a unitary construction therewith to define corresponding flow passages therebetween;
- said disk rim includes fluted inner flowpath channels for bounding said passages circumferentially between pressure and suction sides of adjacent ones of said blades and axially between leading and trailing edges of said blades, with each of said fluted channels diverging radially outwardly and varying in circumferentially arcuate contour axially between said rim forward and aft ends, and joining said blades at corresponding arcuate fillets;
- said disk rim further including integral stubs each having a weld plane welded to a planar root of a corresponding blade, and said weld plane is disposed in said fillets;
- and
- said weld planes vary in radial distance from said fluted channels axially between said rim forward and aft ends.
