초록

The invention relates to aerodynamically matching the rear fan of a turbojet having two fans and a low-pressure compressor at the front of the intermediate casing, said fans being driven by two independent shafts. Said compressor is disposed between the blades of the two fans and includes at least one ring of rotor blades around the periphery of a wheel driven by the drive shaft for the front fan, and at least two grids of stator vanes disposed on either side of the ring of rotor blades and inside a grid carrier ring. A stationary outer grid and a stator...

What is claimed is: 1. A three-spool by-pass turbojet with a high by-pass ratio, the turbojet having a front fan and a rear fan at the front of an intermediate casing that presents an outer structural grid in the by-pass air flow and an inner structural grid in the main air flow, the fans having blades that extend radially outwards to a fan casing, which fan casing defines the outside of the by-pass air flow, the turbojet also having a low-pressure compressor for compressing the air coming into the channel for the main air flow, said front fan and said ...
