3D Deformation measurement of a rotating blade

The 3D deformation of a rotor blade is measured with Q400 3D-DIC system. The cameras are precisely synchronised to the rotation (4/sec)

The image shows the color coded out-of-plane deformation and the measurements along a polygon line.

This application example shows that the deformation of a rotor blade can be separated from the rotational movement of the rotor. Such measurements can also be carried out underwater on ship propellers.
