In https://en.m.wikipedia.org/wiki/History_of_aviation there are the following:

* Sir George Cayley was first called the "father of the aeroplane" in 1846... Among his many achievements, his most important contributions to aeronautics include:

Conducting scientific aerodynamic experiments demonstrating drag and streamlining, movement of the centre of pressure, and the increase in lift from curving the wing surface.

* In 1871 Wenham and Browning made the first wind tunnel.

So no the Wrights didn't figured out that curved wings can produce enough power to lift the aircraft and no it was not a first to use wind tunnel experiments.
