Abstract
A turbine engine includes a gear driven booster connected to a high pressure shaft of the engine. A gear assembly connects the booster to the high pressure shaft. The booster is a high speed orthogonal booster that includes a plurality of rotor blades and a plurality of stator vanes. The booster rotates in a direction that is opposite to a direction the high pressure shaft rotates.
Claims19
A turbine engine comprising:
- a first turbine;
- a booster located upstream of said first turbine;
- a first shaft including a first end portion and a second end portion, said shaft extending from said first turbine and connected to said first turbine at said first end portion;
- a first gear assembly connecting said booster to said first shaft at said second end portion;
- and
- a compressor upstream from said first turbine, said compressor connected to said first shaft.
A method for assembling a turbine engine, the turbine engine including a high pressure shaft connecting a high pressure turbine to a high pressure compressor, and a booster shaft connecting a booster to a gear assembly, said method comprising the steps of:
- connecting the gear assembly to the high pressure shaft;
- and
- connecting the booster shaft to the gear assembly so that the booster shaft rotates at a different speed than the high pressure shaft.
