Rotating Wing Activities in Germany during the period 1939-1945
 

The following are two ‘pdf’ files on Rotating Wing Activities in Germany during the period 1939-1945.

They may provide information of interest on specific early gyrocopters and helicopters for some.

Dave,

this is marvelous stuff!!! One thing that puzzles me is the dismal failure of the Fw 186, an autogyro which didn't seem to introduce any radical innovation, while the very innovative Flettner and Focke Wulf helicopters were such outstanding aircraft. Perhaps the engineers at Focke Wulf were ordered to screw up the 186....??? (Ok, just a wild guess).

Thanks for posting this!

Thanks Dave !!! Very interesting stuff !!

Interesting stuff.

One of the more interesting aspects is the near universal use of the NACA 230 series of cambered airfoils for rotors.

Here’s a view of the Doblhoff rotorhead.

The double row spherical bearing connecting rotor hub to airframe permits the rotor hub to self-align with the tip plane axis, eliminating the need for flap and drag hinges.

In Wikipedia ~ Focke-Wulf_Fw_186 it says; ".... However only one prototype of the aircraft was constructed, and the project was abandoned when the RLM preferred the Fieseler Fi 156 Storch over the Fw 186."

Arnie, if the computer didn't come with an additional pair of hands/arms their claim is bogous... you'll not be able to do more than one thing at a time....;-)

Hi Arnie,

You probable made a good choice. They say that desktops are declining in acceptance.


Juergen is the one providing most of the new information. http://www.unicopter.com/ThumbsUp.gif
