Can someone explain to me how the Adverse Pressure Gradient affects the position of the Transition Point. I am covering Zero Lift Drag and whilst I understand how Surface condition, speed of flow and size affect the TP I just don’t see how the adverse pressure gradient does. The explanation in AP3456 is very short and whilst it explains what it is that is as far as it goes.
Does this make sense to any one out there, if so, please help.
