4.6.2.2 open rotor

An open rotor is a type of propulsion system that features a rotor or fan without a traditional duct or shroud. Unlike ducted fans, open rotors have exposed blades that operate in free air, generating thrust through the acceleration of air rearward.
Open rotors are designed to be more efficient at high speeds and can offer advantages such as, reduced weight and complexity compared to ducted fans, improved thrust-to-weight ratio, increased efficiency at high speeds, potential for reduced fuel consumption and emissions.
However, open rotors can also produce more noise and may be more susceptible to foreign object damage (FOD) due to the exposed blades.
