I have been recently studying the shapes and characteristics of different high-lift airfoils that have been used for VTOL aircrafts. While studying these different designs today, a particular quadrilateral-shaped airfoil design popped into my mind and I am now very curious to know if this airfoil shape would be ideal as a high-lift airfoil for a VTOL aircraft, either as an airplace wing for a VTOL aircraft, or perhaps as a rotor blade for a high-lift helicopter.
I believe this airfoil should produce lift even though it will have a zero angle of attack as it moves through the air.
Please reference the following drawing:
It will produce a lot of drag but at the same time I believe that the air pressure differential should produce a lot of lift.
Would this quadrilateral-shaped airfoil produce lift with a zero angle of attack?
I have changed the main question from 'Would this quadrilateral-shaped airfoil be ideal for VTOL aircraft?' to 'Would this quadrilateral-shaped airfoil produce lift with a zero angle of attack?' because this is really the particular answer that I am seeking.
