Abstract
A generator arrangement includes a generator and a pneumatic turbine. The pneumatic turbine is operably connected to the generator. A gas turbine engine compressor section is in fluid communication with the pneumatic turbine through a bleed air conduit to provide pressurized air to the pneumatic turbine for applying mechanical rotation to the generator.
Claims17
A generator arrangement of a power system, comprising:
- a first generator assembly having a first pneumatic turbine operably connected to a first generator;
- a second generator assembly having a second pneumatic turbine operably connected to a second generator;
- a first bleed air conduit fluidly connecting a first gas turbine engine with the first generator assembly;
- a second bleed air conduit fluidly connecting a second gas turbine engine with the second generator assembly, a first and a second coolant conduits providing a bleed air flow of high pressure air discharged by the respective first and second gas turbine engine in the same direction to the first and second respective generator assemblies;
- a crossover conduit connected between the first bleed air conduit and the second bleed air conduit;
- and
- a crossover valve disposed along the crossover conduit configured to control the bleed air flow in the crossover conduit to selectively place both of the first and second generator assemblies in fluid communication with a common compressor section of the first and second gas turbine engines.
