Turbomachine has a double body, with double sample power

摘要

The turbo-machine (11) has a high-pressure body (12) and a low-pressure body (13) arranged along a common axis, and respectively comprising two coaxial common shafts (14, 15) coupled to two coaxial movement transmission shafts (33, 38) transversely extending the shafts of the bodies. An auxiliary gear-box (19) comprises a shaft (21) coupled to a starter. Controllable selective coupling units (50) are intercalated between the shaft (21) and the shafts (33, 38) to connect the shaft (21) respectively to the shafts (33, 38) during the starting phase and operating phase.
