Titasse is on a distinguished road

I try to create a 2D simulation for an innovative wind turbine with moving blade. For steady blades, I used to create 3 different fluids separate by interfaces to implement sliding mesh. The center with no motion, the rotating part to simulate the rotation of the wind turbine and the third one for the outside domain.

But now, i create a new fluid just around the airfoil to simulation the rotation of the blades around their own axis. Everything is ok, my airfoil is moving well as my wind turbines but if i check on Solve -> Mesh Motion, the contact is not guarantee. Maybe because the rotation axis of the airfoil has to be steady. How can I keep the contact at the interface ? I can send you the .cas file if you want.
