Abstract
A drivetrain for a multi-spool counter rotating gas turbine engine may include a lay shaft for connecting a power turbine shaft of the engine with a gas generator shaft of the engine when the drivetrain is in engine start mode. In normal operation mode, an actuator disengages the lay shaft, thereby allowing free and independent rotation of the power turbine shaft and the gas generator shaft.
