Mentour Pilot did a video about the CFM RISE open fan engines a few months ago, they’re somewhere between a turboprop and a geared turbofan. Able to cruise at turbofan speeds, but much higher bypass ratios like turboprops. They’re not technically new, but they’re possible now due to material advances. Pretty cool concept.
