Propfan

A propfan, also called a propjet, an open rotor engine, or an open fan engine, is an aircraft engine combining features of turbofans and turboprops. It uses advanced, curved propeller blades without a duct. Propfans first started prototype testing in the 1970s, aiming to combine the speed capability of turbofans with the fuel efficiency of turboprops…
