Abstract
A shaft system includes an outer shaft including an outer surface and an inner surface defining a conduit and an inner shaft extending along at least a portion of the conduit. The inner shaft includes a radially extending passage. The inner shaft has a first end and a second end that is opposite the first end. An input member is arranged at the first end of the inner shaft. A thrust damper is arranged between the input member and the inner shaft. The thrust damper constrains relative rotation between the inner shaft and the outer shaft.

A shaft system comprising:
- an outer shaft including an outer surface and an inner surface defining a conduit;
- an inner shaft extending along at least a portion of the conduit, the inner shaft including a radially extending passage, the inner shaft having a first end and a second end that is opposite the first end;
- an input member arranged at the first end of the inner shaft;
- and
- a thrust damper arranged between the input member and the inner shaft, the thrust damper configured to constrain relative rotation between the inner shaft and the outer shaft.
An aircraft system comprising:
- an air breathing engine including a compressor, a turbine mechanically connected to the compressor, and a combustor fluidically connected to the compressor and the turbine;
- a gearbox mechanically connected to the turbine;
- a generator;
- and
- a shaft system operatively connecting the gearbox and the generator, the shaft system including:
- an outer shaft including an outer surface and an inner surface defining a conduit;
- an inner shaft extending along at least a portion of the conduit, the inner shaft including a radially extending passage, the inner shaft having a first end and a second end that is opposite the first end;
- an input member arranged at the first end of the inner shaft;
- and
- a thrust damper arranged between the input member and the inner shaft, the thrust damper configured to constrain relative rotation between the inner shaft and the outer shaft.
