Focke-Achgelis projects

[hesham]

during the 1945,Focke-Achgelis worked on a heavy helicopter with an increased loading
capacity ?.

Maybe this one, found on http://paralympic-ph.com/germanvtol/fockeachgiles/284folder/233z.jpg ?
Not a "Zwilling in the sense of, say, the He 111Z, but more logical. And it's designated Fa 223Da
on that site (http://paralympic-ph.com/germanvtol/fockeachgiles/284folder/fa284.html, sorry, had
a typo in the file name), not sure what it meant, maybe "Doppel Antrieb", because it used two
complete dynamic systems, but it could as well have had no special meaning at all. At least, this
designation is mentioned in several sources, whereas "Fa 223Z" is unconfirmed, as Skyblazer correctly
pointed out.

From Waffen-Arsenal band 128.

 

[hesham]

Also from the same source (Waffen-Arsenal band 128);


the Focke-Achgelis Fa.267 was developed from Fa.223 as anti-submarine and transport
helicopter project,also used as an ambulance helicopter,but the development terminated.

The zwilling project depicted above is called the Fa 325 Krabbe in other sources, and described as a 1943 project. Here is another picture of it.

As Maveric requested;

the source for Focke-Achgelis E.6 which led to develop Fa.223 is the book;
Helicopters of The IIIrd Reich

 

[Maveric]

Thanks, very interesting found!

BTW, I would recommend to attach drawings from such patents, additionally to a direct link.
In this case, the link gives a description, for the drawing, you have to choose "Volldokument
laden", probably not obvious to everybody.

Hi everybody

I have a few questions about the Fa 223 / Krabbe.
Why is a helicopter a better torpedo carrier than an airplane ?
Where is this quad flak located ?
Why only one torpedo ? For such a big helicopter !

Where is the Cockpit located ? In the first fuselage or the second ?

Maybe someone can draw such a flying S-Boot with one torpedo or the flak ?

Many greetings and many Thanks in advance

Modern navies use Helicopters for short-range, anti-submarine missions because helicopters can land on tiny flight decks. Torpedo carrying really only became practical when turbine engines were perfected during the 1950s.
Naval helicopters are also handy for cross-decking personnel and supplies (e.g. mail) medical emergencies, landing small raiding parties, search and rescue, etc.

I think that this drawing depicts the rescue basket used by the operational Fa.223.

In addition to the side by side twin-rotor formula, Heinrich Focke have studied plenty of different solutions for anti-torque on helicopters, as shown by his patents:

 

[PhR]

Heinrich Focke was particularly interrested in the twin-rotor antitorque "Butterfly" formula and he continued after the war in France and in Germany: https://www.secretprojects.co.uk/threads/sncase-sud-est-aviation-projects.3178/page-3#post-689405
