It looks like VasyFan may have the answer to all those trying to design a ducted fan powered aircraft. Their latest fan is a 570 mm diameter unit with over 300 lbs of thrust. I sent an inquiry to them and got the following reply:
"
thank you for contacting us and considering VasyFan. Our product VF-570mm is under development, at the moment we do not have much information beyond the measurements you have seen on the site and estimated weight about 28/30 kg with the REX90 60kw motor.
I believe that in less than 2 months we will have the first prototype ready to carry out the various continuous thrust and peak thrust tests.
This Edf 570mm vera used together with the MGM HBC400400 ESC with 400V batteries.
As for the price, we are around 20,000 euros VF-570 + REX90 + HBC400400.
In our opinion it is a fairly low price compared to a jet engine of equal thrust which costs over 60,000 euros."
Time to rev up the Solidworks. This is considerably more thrust than the SubSonex engine produces and with the high fuel consumption of small jet engines you might be able to carry enough batteries to get out of sight of your airport.
For those designing twin jet aircraft Vasyfan already makes a 390mm unit with a 45 kw motor that develops 58 kg of thrust.
