Investigating Aerofoil Lift: Can Plasticine Be Used? | IB Coursework Project

[jiggy]

I am doing a project for my IB coursework investigating lift on aerofoils with different shapes. I was wondering if plasticine can be used as an aerofoil.
I am designing aerofoils of different shapes such as camber , cuboid , sphere , etc. For modelling them , I have used plasticine instead of polystyrene I have done experiments using plasticine and have gotten results. but I am not too sure if plasticine is an accepted aerofoil to do the experiment with. my experiment is pretty low-tech using a very basic wind tunnel

anyone?!

Provided the airflows through your wind tunnel are mild enough to prevent deformation, and provided you can mold to the plasticine to exact tolerances with very smooth surfaces, it can be used to test small-scale airfoils. It would at some point deform under it's own weight if you scaled it up too far, however.
