Abstract
A bearing assembly for an engine is disclosed. The bearing assembly includes a first structure, a second structure that is movable relative to the first structure, and a foil membrane disposed between the first structure and the second structure. The foil membrane includes at least one perforation that supplies liquid fuel in a region between the foil membrane and the second structure, where the liquid fuel is combusted by the engine.

2 more elements
A system for an engine, comprising:
- a fuel tank;
- at least one pump that provides liquid fuel from the fuel tank to a nozzle of a combustion section of the engine;
- and
- a bearing assembly that includes
- a first structure;
- a second structure that is movable relative to the first structure;
- and
- a membrane disposed between the first structure and the second structure, wherein the membrane includes a plurality of perforations that receive liquid fuel from the at least one pump and supply the received liquid fuel in a region between the membrane and the second structure.
5 more elements
An engine comprising:
- a case;
- a shaft;
- an inlet;
- a compressor section that compresses air received at the inlet;
- a combustor section that combusts a mixture of compressed air provided by the compressor section and fuel;
- a turbine section that extracts energy from combusted mixture to drive the compressor section via a rotation of the shaft, where the shaft couples the compressor section and the turbine section;
- and
- a bearing assembly that supports the shaft, the bearing assembly including a membrane disposed between the shaft and the case, wherein the membrane includes at least one perforation that supplies liquid fuel to a region between the membrane and the shaft.
