Hi can somebody please explain to me what's the difference between optimization simulation of turbomachinery and NACA0012/OneraM6 cases?

For NACA0012/OneraM6 cases, we have some objective function like Drag which we are minimizing by changing the shape.

Isn't it similar for the case of turbines or compressors? There we just want to minimize/maximize the torque or pressure loss etc. by changing the shape? So, turbine/compressor's blade is also a aerodynamic wing in a sense?

What am I missing?

Sorry, I'm new to the field that's why asking such a question.
