Turbomachine e.g. jet engine, for aircraft, has connection unit with air flow annular channel centered on longitudinal axle, where channel is traversed by oblique torque arms connecting internal units with streamline annual cases

摘要

The turbomachine has a connection unit with an air flow annular channel (76) centered on a longitudinal axle (40). The channel is externally determined by internal surfaces (54, 68) of streamline annual cases (52, 66) of open rotor type upstream and downstream contra-rotating propellers (26, 28), and is internally determined by internal units (42, 44) of the propellers. The channel is traversed by oblique torque arms (50, 64) connecting the internal units with the cases.
