摘要 |
A gas turbine engine (10) has a compressor (14) which includes a rotary stage (16) supported for rotation by a plurality of wire wound stators (34). When the stators (34) are electrically energised, they exert Maxwell type magnetic forces on a magnetically permeable ring (18) joining the tips of compressor blades (21) in the stage (16), and lift it into a position in space where it can rotate on a common axis with the turbine of the engine (10).
