摘要： A gas turbine engine includes a very high speed low pressure turbine such that a quantity defined by the exit area of the low pressure turbine multiplied by the square of the low pressure turbine rotational speed compared to the same parameters for the high pressure turbine is at a ratio between about 0.5 and about 1.5. The high pressure turbine is supported by a bearing positioned at a point where the first shaft connects to a hub carrying turbine rotors associated with the second turbine section.

摘要： A gas turbine engine includes a fan section, a gear arrangement configured to drive the fan section, a compressor section and a turbine section. The compressor section includes a low pressure compressor section and a high pressure compressor section. The turbine section is configured to drive compressor section and the gear arrangement. An overall pressure ratio, which is provided by a combination of a pressure ratio across said low pressure compressor section and a pressure ratio across said high pressure compressor section, is greater than about 35. The pressure ratio across the low pressure compressor section is between about 3 and about 8 whereas a pressure ratio across the fan section being less than or equal to about 1.45.

摘要： A gas turbine engine includes a first spool, a first gear system connected to and driven by the first spool, a second spool, and a second gear system connected to and driven by the second spool. A first starter-generator has a first shaft with a switchable coupling connected to the first shaft. The switchable coupling selectively couples the first starter-generator to the first gear system when the switchable coupling is in a first position and selectively couples the first starter-generator to the second gear system when the switchable coupling is in a second position.
