Even at a hypothetical level, it is beyond me how this thing flies. Any insight?

Like a helicopter, but I don't see any way to cancel the rotor torque.
-
Rotor torque may not be canceled if the pilot is sitting in some kind of non rotating middle part. Sort of a ring inside the rotating ring.
-
Wouldn't the pilot get dizzy? :)
:rolleyes:
-
It'd have to be a gyrocopter.
Possibly with much the same idea behind it as the carter copter.
-
or 2 sets of blades, rotating in oposite directions.
kind of like the old
'egg-beater' chopper that didn't have a tail rotor
(or is that what you meant by 'carter-copter'?)

Not if the middle part of the "thing" doesn't rotate frank ;)

i saw one fly at an airshow,,,,, i think it was on Neptune, ya know Neptune in the winter is really quite nice. It was doing fountain maneuver with i think a ..ummm Klingon battle cruiser.

on the websight that picture shows them around a B-29. If they were built by wars end would it have been able to keep up with the bomber? Even by todays standards 200 is fast for a helicoptor.
-
It's fictional, not a real German project.
-
This is actually a quite advanced design I have seen from DiVinchi and other flight Designers.
How it works is where the pilot is sits stationary. The Blades rotate like that of a helicopter and by turning the blades slightly you can vector the thrust so you can go forewards, reversed, side to side, up, and down. You could even roll the aircraft.
Now it will work if you can get the right powerplant and torque for it, however the problem being the central fuselage might spin uncontrollably.
Still, I would fly one in a heartbeat.
-
From the picture, it seems like the disc is using rockets to maintain the rotation around the stable cockpit. The blades must follow some kind of path that only lets them create forward movement lift (angles and such). The only problem is tremendous torque.... Maybe there was a constant rocket firing in a set counter direction?
I'm not sure if this is even a valid Luftwaffe/Nazi theoretical design. It just piqued my curiousity....

The funniest part:
"This could conceivable
saw enemy bombers!" [/color][/i][/b] :rofl
-
Why waste engine thrust countering torque?
Spin up the blades on the ground, remove power from them, use the stored energy to take off vertically without power. Fire up the jet engine and convert to flight as an autogyro.
A design like that operated as a helicopter seems dicey to me. An autogyro seems like a more realistic and better performing choice.
-
Anyone else grateful the war ended in 1945?
-
Torque in a helicopter is effected more by the gearbox that drives the main rotor than the main rotor itself. This is evidenced by autorotation in a normal helicopter. Once the power is removed the torque drops off dramatically.
This could conceivably work, provided that no torque was created in driving the rotor blades.
Cheers,

Anyone else think that if it didn't the Luftwaffe would have really have had the resources to waste on fantasy planes? :D
-
IMO, from an aircraft design standpoint, there was no real point to continue the war as the f4u was already in use. ;)
-
The fantasy writer alludes to the factory workers acting as volunteer pilots. I recall reading where workers at the plant making the Heinkel "Salamander" jets actually flew them in defense of that plant. Has anyone else come across this?
-
I think that the United States today (2003) would have a VERY hard time building and flying one of those. Nazi Germany, even if it werent being bombed, could not have made that thing fly.
