Thanks PuntoSaurus,
If you learnt under Mike, you could be a good contact for me. I may direct some questions to you if you don't mind.
1. Ah, now I understand.
2. Confusion alert. This is where misreading something can lead to all sorts of problems. Aint aerodynamics wonderful and you can bend the rules through interpretation.
3. My picture is... (Airfoil leading edge towards thrust)
(Aarrgghhh. EDIT. Added dots to format picture. Ignore dots...)
...................LIFT
.....................A
.....................|
DRAG..............|...............THRUST
<-------- (airfoil blade) --------->
.....................|
.....................|
.....................V
................WEIGHT
If you learnt under Mike, do you have a similar picture. What would the picture be in relation to. To me, that is the 4 forces on an airfoil section.
Thanks for the other points.
My original notes have it in 3 columns, but not much supporting information.
It is a few years since I was taught and having no experience since has obvious brain fade.
