Abstract
An electric power generation system (EPGS) employs both a wild-source generator and a variable and/or constant frequency generator. The wild-source generator is coupled to receive mechanical power from a low-pressure spool on an aircraft engine and to generate in response a wild-source output for consumption by voltage and frequency-tolerant loads. The variable and/or constant frequency generator is coupled to receive mechanical power from a high-pressure spool on the aircraft engine and to generate in response a variable and/or constant frequency output for consumption by voltage and frequency-intolerant loads.
Claims9
An electric power generation system (EPGS) comprising:
- a wild-source generator coupled to receive mechanical power from a low-pressure spool on an aircraft engine and to generate in response a wild-source output for consumption by voltage and frequency-tolerant loads, wherein the wild-source output is voltage unregulated and speed unregulated;
- and
- a variable-frequency and/or constant frequency generator with regulated voltage output coupled to receive mechanical power from a high-pressure spool on the aircraft engine and to generate in response a variable and/or constant frequency output for consumption by voltage and frequency-intolerant loads.
An electrical power generation and distribution system (EPGDS) comprising:
- an aircraft engine having a low-pressure spool and a high-pressure spool;
- a wild-source generator coupled to receive mechanical power from the low-pressure spool and to generate in response a wild-source output that is voltage unregulated and speed unregulated;
- a variable-frequency and/or constant frequency generator coupled to receive mechanical power from the high-pressure spool and to generate in response a regulated voltage output with variable/constant frequency;
- at least one voltage and/or frequency-tolerant load connected to receive the wild-source output generated by the wild-source generator;
- and
- at least one wild-source intolerant load connected to receive the regulated voltage with variable/constant frequency output generated by the variable-frequency and/or constant frequency generator.
