Abstract
Abstract In order to obtain a low-cost, light-weight automotive gas turbine plant, the latter is provided with a compressor operating on a first shaft and a turbine operating on a second shaft formed as an element separate from that of the rotor. An infinitely variable transmission interconnects the first and second shafts and ensures that sufficient power for any operational condition is transferred from the turbine to the compressor.

Claim 1
Independent Claim
230 words
In an automotive gas turbine power plant for a vehicle provided with wheels, including a turbine having a rotor, a first shaft, the turbine rotor being mounted on the first shaft, a compressor having a rotor, a second shaft separate from the first shaft, the compressor rotor being mounted on the second shaft, and transmission means interconnecting the first and second shafts adapted to transmit the power required for driving the compressor as well as to a power transfer shaft operably connected to the wheels of the vehicle, the improvement of a first reduction gear of the planetary type in the transmission means, said planetary gear having one input means and first and second independent output means, an infinitely variable transmission member connected to the first output means of the planetary gear for transferring power to the second shaft mounting the compressor in response to the occasional load upon the plant, and a second reduction gear including a reversing step connected to the second output means of said planetary gear for transferring power to the power transfer shaft, the first and second shafts being aligned in a horizontal direction, and the planetary gear is of the differential type having stepped planetary gear wheels, the input means including one sun wheel, the first output means including a second sun wheel, and said input means and first output means including concentric components.
