If this blade project makes it into service around the same time as the ultra fan engine, we would have a deadly combination.
Sounds like it is geared toward a narrow body. My guess is that this could be testing for the A320 family replacement.
The test campaign is expected to go through next year with a total of 120 to 150 hours.

And that outer part is designed to be 2/3rds the size of a narrow body wing.

The speed will increase as the test campaign progresses.
This is a very informative article that KarelXWB shared in the other thread.
