Suitable mechanism for changing the angle of attack of an airfoil

[swieity]

I have to conduct wind tunnel test on a naca0015 symmetric airfoil at different angles of attack and I am in search of a suitable mechanism to change the angle of attack of the airfoil.Please help.

There are many, many papers written on the subject. I'd suggesting looking a few up.

Ever heard of a 4-bar mechanism? Or a stepper motor? This seems like a very straightforward problem to me...
