Hi, I'm right now coursing IB (equivalent to A-levels) and one of the compulsory essays we must do is called Extended Essay. It's an essay you do on a topic you choose. I choose aerodynamics. Created a "wind tunnel" out of plastic and made it rigid with hard plastic pieces which were partially flexible, and I also created a wing out of balsa wood. Now, I calculated the lift assuming the acceleration was uniform to then use the uniformly accelerated equations, which were then displayed in force diagrams. However my results when plotting lift generated vs angle of attack it gave me the optimum angle 45º, and the shape of the graph was an inverse x^2, clearly it is not the correct graph.
I know the results must be innacurate due to my assumptions, but does anyone know how to calculate the lift with another methodology?
I also use the modern lift equation but I want experimental datas :)
Thankss
