Taking the P
Has anyone measured P effect?
This is the effect of airflow coming into the prop slightly sideways when you are tail down and moving and alters the thrust from one side of the aircraft to the other. Now intuition says the coarser side will give more thrust but is this so? Part of the blade will be stalled when the aircraft is moving slowly so I wonder how real the actual effect is. Also the amount the airflow bends as it enters the prop disk will reduce the effect.
So any real testing been done?
