Turbo engine e.g. aircraft engine, has fan-rotor driven into flow channel, another rotor arranged downstream to former rotor, and booster-compressor with booster-rotors that are connected with respective fan-rotors in rotating manner

摘要

The engine has a fan-rotor (14) driven into a flow channel (11) in a rotating manner, and another fan-rotor (32) arranged downstream to the former rotor and driven in an opposite direction to the former rotor. A booster-compressor (40) arranged between the fan-rotors has booster-rotors (41, 42) that are connected with the respective fan-rotors in a rotating manner. The latter fan-rotor is connected with a tubular spinner (18) that supports one of the booster-rotors at its front side. The fan-rotor (14) is attached to a hub-body connected with a rotating shaft (13).
