摘要

The retainer (30) has two rotary assemblies (32a, 36a) comprising two propellers (32, 36), two turbines (34, 38) and two structural rotating device (33, 37), respectively. A support structure (60) comprises a support unit (62) that is carried by a set of anti-friction bearings (64, 66). Another support structure (68) is carried by another set of anti-friction bearings (70, 96). The former structure comprises another support unit (84) that is carried by an antifriction bearing inter-turbine (72), where two ends of the latter support unit is mounted on one of the turbines.
