Abstract
Abstract A drive line for a gas turbine engine having an integrated diffuser, a regenerator section, a burner and gasifier section, a power turbine section and a power transmission assembly, power input elements of the power transmission assembly being connected drivably to the power turbine and power output elements thereof being connected to an output shaft extending in parallel disposition with respect to the power turbine shaft and through the gas turbine diffuser housing, the diffuser blades being modified to accommodate the output shaft whereby the overall dimensions of the engine and drive line are reduced to a minimum.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
A gas turbine powerplant and transmission assembly comprising a main housing, a centrifugal compressor in said housing, a gasifier turbine drivably connected to said compressor, a power turbine in axial disposition with respect to said gasifier turbine, a power turbine shaft mounted for rotation about an axis that is common to the axis of said compressor, a planetary transmission in a portion of said housing remotely situated with respect to said compressor, diffuser vanes arranged in said housing in the radially outward region of said compressor, gearing drivably connecting said power turbine shaft with power input elements of said transmission, a power output shaft connected to driven elements of said transmission and extending through said housing, said output shaft being journaled at spaced portions of said housing and arranged in parallel disposition with respect to said power turbine shaft axis, the spacing of said power output shaft from said power turbine shaft axis being less than the radial distance from said axis to the outermost portions of said diffuser vanes, one of said diffuser vanes having an arcuate thickness that is substantially greater than the corresponding thickness of the adjacent diffuser vane, and an opening formed in said enlarged diffuser vane, said power output shaft being received in said opening and extending therethrough to the exterior of said housing.
Claim 2
Dependent Claim
219 words
A gas turbine powerplant and transmission assembly comprising a main housing, a centrifugal compressor in said housing, a gasifier turbine drivably connected to said compressor, a power turbine in axial disposition with respect to said gasifier turbine, a power turbine shaft mounted for rotation about an axis that is common to the axis of said compressor, a planetary transmission in a portion of said housing remotely situated with respect to said compressor, diffuser vanes arranged in said housing in the radially outward region of said compressor, gearing drivably connecting said power turbine shaft with power input elements of said transmission, a power output shaft connected to driven elements of said transmission and extending through said housing, said output shaft being journaled at spaced portions of said housing and arranged in parallel disposition with respect to said power turbine shaft axis, the spacing of said power output shaft from said power turbine shaft axis being less than the radial distance from said axis to the outermost portions of said diffuser vanes, one of said diffuser vanes having an arcuate thickness that is substantially greater than the corresponding thickness of the adjacent diffuser vane, and an opening formed in said enlarged diffuser vane, said power output shaft being received in said opening and extending therethrough to the exterior of said housing.
Claim 3
Dependent Claim
168 words
The combination set forth in claim 1 wherein said transmission assembly comprises a pair of planetary gear units, each gear unit comprising a ring gear, a sun gear, a carrier and planet pinions carried by said carrier in meshing engagement with said sun and ring gears, the sun gear of the first of said units being connected drivably to the power turbine, means for anchoring the carrier of said first gear unit during reverse drive range operation, selectively engageable brake means for anchoring the ring gear of the first gear unit during low speed ratio operation whereby said ring gear acts as a reaction point, means for connecting drivably the ring gear of said first unit and the sun gear of the second gear uniT during low speed ratio operation, the carrier of the second gear unit being connected drivably to said power output portion of said assembly and the means for connecting together two elements of said second gear unit for rotating in unison during high-speed operation.
Claim 4
Dependent Claim
97 words
The combination as set forth in claim 2 wherein the means for connecting the ring gear of said first gear unit and the sun gear unit of said second gear comprises an overrunning clutch, said overrunning clutch having an outer race connected to the ring gear of the first gear unit and an inner race connected to the sun gear of the second gear unit, said overrunning clutch accommodating torque distribution from the ring gear of the first gear unit to the sun gear of the second gear unit but preventing torque distribution in the opposite direction.
Claim 5
Dependent Claim
78 words
The combination set forth in claim 3 wherein the means for connecting the ring gear of the first gear unit and the sun gear of the second gear unit includes, in addition to said overrunning clutch, a selectively engageable friction clutch adapted to establish a bypass torque flow path around said overrunning clutch thereby accommodating torque distribution in both directions between the ring gear of the first gear unit and the sun gear of the second gear unit.
Claim 6
Dependent Claim
104 words
The combination set forth in claim 3 wherein the brake means for the carrier of the first gear unit comprises a pawl carried by said housing, a pawl disc having external teeth on the carrier, the pawl being engageable with said teeth to establish a reaction point for said carrier of said first gear unit, sun gear for the second gear unit and the inner race for said overrunning clutch including a second pawl disc with external teeth formed thereon, said external teeth being adapted to engage a second pawl to establish a locked condition when it and said previously mentioned pawl engage simultaneously.
Claim 7
Dependent Claim
104 words
The combination set forth in claim 4 wherein the brake means for the carrier of the first gear unit comprises a pawl carried by said housing, a pawl disc having external teeth on the carrier, the pawl being engageable with said teeth to establish a reaction point for said carrier of said first gear unit, sun gear for the second gear unit and the inner race for said overrunning clutch including a second pawl disc with external teeth formed thereon, said external teeth being adapted to engage a second pawl to establish a locked condition when it and said previously mentioned pawl engage simultaneously.
