I'm looking for the calculation of the theoretical maximum lift a series of wings can provide with the venturi effect. I remember a pdf showing the design. Does anyone know who did it or what I should be looking for ?

17º angle of attack is your best rate of climb, slats, flaps and all the other humdinger high lift devices only alter the angle of attack.

wings dont work by venturi effect alone

no but it was increasing the lift coeffecient over 4. I remember several wings profiles slightly angled and reducing in size after each other. It's just that it's supposed to be an optimum if I recall correctly and I don't remember the physicist who made the model

Its not venturi effect. Air hits below wing thus wing, thus aircraft goes up and slightly back. But as propeller pushes more forward, it flies.
