Abstract
An annular turbine frame has ring disposed coaxially about an axial centerline axis and includes a plurality of circumferentially spaced apart ports. A plurality of circumferentially spaced apart struts are joined radially to the ring by devises on the ring. Each strut has radially opposite first and second ends, and a through channel extending therebetween. Each of the channels is aligned with a corresponding one of the ports. Each of the ports has a port counterbore though a radially outer portion of the port forming a shoulder in the port. A seal is disposed within the port counterbore between the shoulder and the strut.

An annular turbine frame comprising:
- a ring disposed coaxially about an axial centerline axis and having a plurality of circumferentially spaced apart ports;
- a plurality of circumferentially spaced apart struts joined radially to said ring by devises on said ring, each strut having radially opposite first and second ends, and a through channel extending therebetween;
- and
- each of said channels aligned with a corresponding one of said ports;
- each of said ports has a port counterbore though a radially outer portion of said port forming a shoulder in said port;
- and
- a seal is disposed within said port counterbore between said shoulder and said strut.
An annular turbine frame comprising:
- a ring disposed coaxially about an axial centerline axis and having a plurality of circumferentially spaced apart ports;
- a plurality of circumferentially spaced apart struts joined radially to said ring by bolts, each strut having radially opposite first and second ends, and a through channel extending therebetween;
- and
- each of said channels aligned with a corresponding one of said ports;
- each of said ports has a port counterbore though a radially outer portion of said port forming a shoulder in said port;
- and
- a seal is disposed within said port counterbore between said shoulder and said strut.
An annular turbine frame comprising:
- a radially outer structural ring disposed coaxially about an axial centerline axis and having a plurality of circumferentially spaced apart first ports extending radially therethrough,
- a radially inner structural ring disposed coaxially about said centerline axis, spaced radially inwardly from said outer structural ring, and having a plurality of circumferentially spaced apart second ports extending radially therethrough,
- a plurality of circumferentially spaced apart struts joined to said outer and inner structural rings,
- each of said struts having radially opposite inner and outer ends and a through channel extending therebetween;
- and
- said channel aligned with a corresponding one of said first and second ports;
- each of said second ports having a port counterbore though a radially outer portion of said second ports forming a shoulder in said second ports;
- and
- a seal disposed within said port counterbore between said shoulder and said inner end of said strut.
