Реферат: An air vehicle propulsion system incorporates an engine core (10) with a power shaft (24) to drive an outer blade row (12). The power shaft is extends through and is supported by a counter rotation transmission unit (28) which drives an inner blade row (14) in counter rotational motion to the outer blade row. The counter rotation transmission unit exchanges power from the engine core with the shaft. An actuator (34) engages the shaft for translation from a first retracted position to a second extended position.
