Abstract
Abstract A low-cost, light-weight automotive power plant includes a turbine operating on a first shaft and a compressor operating on a second shaft, formed as an element separate from the first shaft. These shafts are arranged at an angle to the horizontal power transfer shaft operably connected to the wheels of the vehicle. An infinitely variable transmission transfers power from the turbine to the compressor, and an angular drive transfers power from the turbine to the power transfer shaft.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
A gas turbine power plant in combination with a vehicle having ground engaging wheels, said power plant operably connected to at least one pair of said wheels by a horizontal drive shaft, said power plant further including: a turbine having a single rotor mounted upon a first shaft and a compressor having a rotor mounted upon a second shaft, said second shaft separate from said first shaft; means for mounting said first and second rotors at substantially the same level, with their shafts substantially perpendicular to the horizontal drive shaft, said first and second shafts arranged at an angle to each other, forming a V; an infinitely variable transmission member for transferring power from said first shaft to said second shaft in response to an occasional load upon the compressor; means for mounting said variable transmission member and said first reduction gearing below said rotors with their associated shafts parallel to said first and said second rotor shafts; and angular drive means for transferring power from the shaft of said first reduction gearing to said horizontal drive shaft.
Claim 2
Dependent Claim
178 words
A gas turbine power plant in combination with a vehicle having ground engaging wheels, said power plant operably connected to at least one pair of said wheels by a horizontal drive shaft, said power plant further including: a turbine having a single rotor mounted upon a first shaft and a compressor having a rotor mounted upon a second shaft, said second shaft separate from said first shaft; means for mounting said first and second rotors at substantially the same level, with their shafts substantially perpendicular to the horizontal drive shaft, said first and second shafts arranged at an angle to each other, forming a V; an infinitely variable transmission member for transferring power from said first shaft to said second shaft in response to an occasional load upon the compressor; means for mounting said variable transmission member and said first reduction gearing below said rotors with their associated shafts parallel to said first and said second rotor shafts; and angular drive means for transferring power from the shaft of said first reduction gearing to said horizontal drive shaft.
Claim 3
Dependent Claim
197 words
A gas turbine power plant in combination with a vehicle having ground engaging wheels, said power plant operably connected to at least one pair of said wheels by a horizontal drive shaft, said power plant including: a turbine having a single rotor mounted upon a first shaft and a compressor having a rotor mounted upon a second shaft, said second shaft separate from said first shaft; means for mounting said first and said second rotors, with their shafts aligned and substantially perpendicular to the horizontal drive shaft wherein said turbine is located on top of the compressor, and a combustor is located on top of the turbine, axially aligned with the same and having its output directed towards said turbine; an infinitely variable transmission member for transferring power from said first shaft to said second shaft in response to an occasional load upon the compressor; a first reduction gearing having an output shaft; means for mounting said variable transmission member and said first reduction gearing below said rotors with their associated shafts parallel to said first and said second rotor shafts; and a bevel gear differential for directly connecting said output shaft and said horizontal drive shaft.
Claim 4
