can ducted propeller produce twice lift compared to opened propeller ?
can ducted propeller produce twice lift compared to opened propeller ? for example if there is an opened propeller with low rpm producing some amount of lift. If we ducted that opened propeller and provide same rpm and power as opened propeller to it will it produce twice lift compared to opened propeller with same rpm and power ?

Not twice but there are no tip vortices to waste energy

Ducting works on wing tip vortices as well as the compressor jet engines.
