| 摘要 |
A cooling system (54, 56, 68) for a core compressor of a turbofan engine is disclosed. Heat produced by the core compressor (50, 52) is transferred in a first heat exchanger (54, 56, 58) located in the core compressor flow path to heat transferring medium and than removed to a second heat exchanger (42, 44) located in a secondary working medium flow path - bypass duct and cooled by the bypass air. A system transfers heat from air compressed in the core compressor to the bypass air and is preferably formed by one or more pressurized liquid heat transferring medium closed-loops. A second heat exchanger may support a cooling system for engine oil using oil to heat transferring medium heat exchanger. |
