I don't know, because I think the whole purpose of a prop is to be a fan.
- lazide 4y agoNo quite. Fans == move air, relative to the thing the fan is mounted to. So a jet engine has fans, because it is moving air into and around the engine, but not using them to move itself around directly (It uses the jet of air created by the thermal expansion from the burning fuel and compressed intake air to do that, mostly). Propeller == moves something through air (or another media like water) directly. Semantics, mostly.
