if I remember correctly what I read, it stated the N2 stage was still supporting Nr, even though throttle was reduced - if there were a seperate freewheeling unit this would not make sense, which led me to wonder if "free" turbines didn't need a seperate unit....evidently not the case..... can anyone figure what the reason for that unrealistic auto performance would be?
