Ducted fans bring with them greater skin friction drag and weight which generally more than negates efficiency gains in propulsion

- airhead969 5y agoWrong. Ducted fans can produce twice as much thrust. https://aviation.stackexchange.com/questions/27416/are-ducted-fans-more-efficient https://aviation.stackexchange.com/questions/27416/are-ducte... The main issue is controllability in cross wind gusts. Solve that problem, such as turbojet-style inlets of the 60's jets and there's real efficiency advantages to be had.
