How to Calculate Thrust From a Ducted Fan
(OP)
hi
can anyone tell me how much power you will need to produce 2000lbs of thrust from 70 inch blades in a ducted fan?
also i take it there will be contra rotating blades to stop the whole setup from spinning?
any help and advice will be appreciated
thanks

You need to know the figure of merit (say 0.5), and the motor power.
