Connedrod,
Don't drink and post.
Do you understand that the oil suply to the prop at 1600 RPM IS AT VERY BEST ONLY JUST in gov range.
Complete rubbish.
However to have the Tq at ZERO Tq and a prop speed of 1600 rpm is impossible. For Zero tq means the gas generator must be stopped. This means no oil px to the power section. This means no oil to the gov. This means Zero oil to the prop.
Complete rubbish also.
You obviously cannot understand what is happening with the power plant IN FLIGHT. All of your experience and knowledge of this power plant is when you are doing static run ups, stationary ON THE GROUND.
What you have claimed may well be true - FOR A STATIC RUN UP, ON THE GROUND.
Zero thrust is only in the Beta condition.
On the ground, during a static run up, yes. But in flight, things are different.
