Abstract
Abstract A double ender powerplant including a first engine having a compressor for producing a downstream axial flow, a combustor, a turbine coupled to the compressor through a shaft, and means for attaching a load coupled to the shaft adjacent and downstream from the turbine; a second engine having a compressor for producing a downstream axial flow, a combustor, a turbine coupled to the compressor through a shaft, and means for attaching a load coupled to the shaft adjacent and upstream from the compressor; and, a generator coupled to each of the attachment means of the first and second engines.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A double ender powerplant, comprising: (a) a first engine having a compressor for producing an axial flow downstream therefrom, a combustor, a turbine which is coupled to said compressor through a first shaft, and means for attaching a load coupled to said first shaft adjacent and downstream from said turbine; (b) a second engine having a compressor for producing an axial flow downstream therefrom, a combustor, a turbine which is coupled to said compressor through a second shaft and a means for attaching a load to said second shaft adjacent and upstream from said compressor; and (c) a generator which is coupled to said attachment means of said first and second engines.
Claim 2
Dependent Claim
112 words
A double ender powerplant, comprising: (a) a first engine having a compressor for producing an axial flow downstream therefrom, a combustor, a turbine which is coupled to said compressor through a first shaft, and means for attaching a load coupled to said first shaft adjacent and downstream from said turbine; (b) a second engine having a compressor for producing an axial flow downstream therefrom, a combustor, a turbine which is coupled to said compressor through a second shaft and a means for attaching a load to said second shaft adjacent and upstream from said compressor; and (c) a generator which is coupled to said attachment means of said first and second engines.
Claim 3
Dependent Claim
242 words
A double ender powerplant, comprising: (a) A first powerplant including: (1) a first compressor for producing an axial flow downstream therefrom; (2) a second compressor positioned downstream of said first compressor; (3) a combustor positioned downstream of said second compressor; (4) a first turbine positioned downstream of said combustor drivingly connected to said second compressor through a first shaft; (5) a second turbine positioned downstream of said first turbine drivingly connected to said first compressor through a second shaft, said second shaft and said first shaft being in concentric arrangement and rotating independently of each other; and (6) means for attaching a load coupled to said second shaft adjacent and downstream of said second turbine; (b) A second powerplant including: (1) a first compressor for producing an axial flow downstream therefrom; (2) a second compressor positioned downstream of said first compressor; (3) a combustor positioned downstream of said second compressor; (4) a first turbine positioned downstream of said combustor drivingly connected to said second compressor through a first shaft; (5) a second turbine positioned downstream of said first turbine drivingly connected to said first compressor through a second shaft, said second shaft and said first shaft being in concentric arrangement and rotating independently of each other; and (6) means for attaching a load coupled to said second shaft adjacent and upstream of said first compressor; and (c) a generator which is coupled to said attachment means of said first and second powerplants.
Claim 4
Dependent Claim
242 words
A double ender powerplant, comprising: (a) A first powerplant including: (1) a first compressor for producing an axial flow downstream therefrom; (2) a second compressor positioned downstream of said first compressor; (3) a combustor positioned downstream of said second compressor; (4) a first turbine positioned downstream of said combustor drivingly connected to said second compressor through a first shaft; (5) a second turbine positioned downstream of said first turbine drivingly connected to said first compressor through a second shaft, said second shaft and said first shaft being in concentric arrangement and rotating independently of each other; and (6) means for attaching a load coupled to said second shaft adjacent and downstream of said second turbine; (b) A second powerplant including: (1) a first compressor for producing an axial flow downstream therefrom; (2) a second compressor positioned downstream of said first compressor; (3) a combustor positioned downstream of said second compressor; (4) a first turbine positioned downstream of said combustor drivingly connected to said second compressor through a first shaft; (5) a second turbine positioned downstream of said first turbine drivingly connected to said first compressor through a second shaft, said second shaft and said first shaft being in concentric arrangement and rotating independently of each other; and (6) means for attaching a load coupled to said second shaft adjacent and upstream of said first compressor; and (c) a generator which is coupled to said attachment means of said first and second powerplants.
Claim 5
Dependent Claim
24 words
The double ender powerplant of claim 2, wherein said first and second powerplants are identical except for the location of their respective attachment means.
Claim 6
Dependent Claim
16 words
The double ender powerplant of claim 2, wherein said first and second powerplants are aligned coaxially.
