Free spinning Turbine
I was wondering if anyone could tell me exactly how a free spinning turbine works? In particular the PW150A.
Its my understanding that in a free spinning turbine setup the prop is not directly connected to the LP or HP compressors, but rather it is only connected to the power turbine which is located aft of the LP and HP turbines.
Therefore If I were to spin the prop on a free spinning turbine system, would the only component to be moving in the engine be the power turbine and associated shaft?
