I’ve seen turboprops in museums and on the internet with around six or eight blades. When I looked on the Wikipedia page for propfan engines, which seems to be another name for an open turbofan, the distinction seemed to be mainly how the blades were shaped (like propellor blades or turbine blades) and how tightly-integrated everything is (you can swap the propeller out on a turboprop).

How many blades do you have to add to a turboprop before it’s promoted to an open turbofan and touted as a major new innovation?
