Abstract
An auxiliary power system comprises two turbogenerators sharing a single combustor for delivery of elevated pressure and temperature gas to both the turbogenerators, a single fuel system for supplying elevated pressure fuel to the single combustor, and a single electronic unit for conditioning the electrical power input and output. The auxiliary power system also comprises first and second recuperator means operating in association with the dual turbogenerators for transferring heat from turbine exhaust to air entering the single combustor. The entire recuperator volume is used in both the single and dual turbogenerator operating modes.
Claims11
An auxiliary power system comprising:
- a first turbogenerator having an associated first turbine, first compressor and first generator mounted on a first high-speed shaft;
- a second turbogenerator having an associated second turbine, second compressor and second generator mounted on a second high-speed shaft;
- a single electronic unit for conditioning externally supplied electrical power for startup/motoring of the first and second turbogenerators;
- a single combustor for delivery of elevated pressure and temperature gas to both the first and second turbogenerators;
- a single fuel system for safely supplying elevated pressure fuel to the single combustor;
- and
- first and second recuperator means operating in association with the first and second turbogenerators for transferring heat from turbine exhaust to air entering the single combustor.
