Gas turbine engine compressor stator arrangement and analysis method |
| abstract |
Within an intake 20 for a gas turbine engine, provision is made through stator vanes 25 in the stator whereby circumferentially varying back pressure 34 from a necessary obstruction 32 can be utilised to balance circumferentially varying forward pressure 21 from the intake 20. A combination of camber variation of stator vanes (45a, Fig 4) and stagger variation of stator vanes (45b, Fig 4) may be utilised in order to achieve a desired momentum balance around the circumference of the intake 20. The obstruction 32, which may comprise a pylon and/or radial drive strut, may be shaped to provide back pressure reflection. A method of analysing a gas turbine in order to determine stator arrangements is also disclosed. |
