1. A rotatable flexible joint for use as a rotary joint in a rotary combustor, said joint comprising:
- a. an outer annular channel having an outer bearing, said outer bearing riding within an outer coupling, said outer bearing being rotatably coupled to said outer coupling by means of a first coupling pin,b. an inner annular channel having an inner bearing, said inner channel riding substantially concentrically within said outer channel, said inner bearing riding within an inner coupling, said inner bearing being rotatably coupled to said inner coupling by means of a second coupling pin.

Abstract
A flexible joint capable of use with an O'"'"'Connor combustor is disclosed. The joint permits at least a 2° flex, allowing for transient misalignments between the combustor and rotary joint, minimizing damage to rotary joint seals.

- 7. A rotatable flexible joint capable of use as a coupling for a rotary combustor to a rotary joint, said flexible joint including an outer annular channel with a first outer coupling engaging one end of said outer annular channel, and a second outer coupling engaging the other end of said outer annular channel, said first outer coupling connecting one end of said flexible joint to a combustor, said second outer coupling connecting the other end of said flexible joint to a rotary joint, said outer annular channel further comprising a section positioned between said first and second outer couplings, said section including a first bearing at one end of said section and a second bearing at the other end of said section, said first bearing riding within said first coupling and being rotatably coupled thereto by means of a first coupling pin, said second bearing riding within said second coupling, and being rotatably coupled there to, by means of a second coupling pin, said flexible joint further comprising an inner annular channel riding substantially concentrically within said outer annular channel, said inner annular channel engaging at its one end a first socket and engaging at its other end a second socket, said first socket being positioned substantially axially with said first outer coupling, said second socket being positioned substantially axially with said second outer coupling, said inner annular channel further comprising a section positioned between said first and second socket, said section including a third bearing at one end and a fourth bearing at the other end, said third bearing riding within said first socket, said fourth bearing riding within said second socket.
