No, the blades don't flatten or stretch at all. They are 30% carbon fiber in a polymer resin.

The pitch changes through out the length of the blade, much like several other EDF rotor designs. You need a high degree of pitch at the center and relax the pitch as you get towards the tips. This keeps the load of the fan more constant instead of having a void in inlet stream.
