Hi all,

I believe this is another "Moeller".

Obviously he wants (or wishes...) to take off vertically:

a) With the propellor alone one will have problems to get enough lift - it
is not for nothing that helicopters use huge "props".

b) IF one gets it off the ground, how is one to counter-act the torque
produced by the lift-prop? Is there a counter-rotating system I did not see
on the website? The flimsy louvers one can see below the prop only seem to
redirect the air front/rear not sideways or like a stator vane.... How does
one control the craft up to the speed where aerodynamic control from the
surfaces is possible?

Probably a "Please give me your money for the heck of it!" proposition!!

Claimed performance numbers makes for amusing reading.

I am afraid. that is all there is!!

Actually, I think the concept is sound. Adverse torque is compensated
for through the deflection of air via louvers below the prop. There
are 5 prop blades 94" long. The prop ain't that small and it is shrouded.
I would love to see it up close.

Counteracting the adverse torque is both simple and ingenious. 
I haven't seen it but from what I am able to gather from the
 writings on the web page they are using louvers below the fan 
to deflect the air, thrust, whatever being produced by the fan. 
They would pivot much like an aileron, and be positioned from the 
center of the hub out to the edge of the fan shroud. I would imagine 
there would be several (maybe 6 or 8 louvers and would literally make 
it possible for the aircraft to rotate 360 degrees in place. It may not 
achieve all of its design specs, max cruise speed, range, etc, but what 
new aircraft design does. You may disagree with me and not believe that 
it will ever leave the ground, or if it does it will be uncontrollable, 
but I am perfectly happy to wait until it goes streaking across the 
sky to prove I am right.
