Very He-100 to me...

 

[Wurger]

I woulkd say the Ki-78 though...

the pic source: Kawasaki Ki-78 (KEN III)

 

[GrauGeist]

I always thought the KI-78 looked more like the Me209 (V4 pictured) and the KI-61 was close the the He100's lines.

 

[Wurger]

Yep... both were quite close in shape.

 

[Shinpachi]

I heard the Ki-78 was developed based on the German aircraft standards.
Project leader Mineo Yamamoto stayed in Germany during 1938-1939 to study.
He kept contact with a Heinkel engeneer in Tokyo even during the war to leave a lot of data to his family in the postwar.
Most of them are not made public yet except Mineo's scholarly papers like this.

Engine mount structure of the Ki-78.
Made of magnesium alloy complied to the German standards AZM.
I have no idea about AZM.

Shinpachi, AZM is one of many alloys the Germans developed, it is comprised of Aluminum, Zinc and Magnesium was a high-stress forged material.
It was used not only for engine mounts, but a great many parts on the DB601 were made from AZM alloys.

Here is a very useful page that has an extensive list of WWII era German Magnesium alloys used on aircraft and I'm sure that the Germans shared these formulas with the Japanese.

Kawasaki Ki-64 not new.

 

[Capt. Vick]

That's an unfinished KUGISHO R2Y1 KEIUN, not a Kawasaki Ki-64

That's correct!
It's hard to mistake the two, as the R2Y1 is a very unique mid-engined aircraft. The one pictured above was the second airframe under construction, the first airframe flew but was destroyed in an Allied air raid.

On a side note, Messerschmitt had a design that was very close to the Yokasuka design, the Me509. It was never built, but was to have elements of the Me309 in it's construction.
This photo is a vintaged scale diarama of the Me509, with a Me309 in the background.

I like a great many Japanese aircraft but that one got hit with the ugly stick...and HARD!

 

[GrauGeist]

What was interesting about the Yokosuka R2Y, was that it was designed to eventually be jet powered.
The Kyushu J7W was another late-war piston powered design that was to eventually be jet powered, too.

The Ki-78 was far more beautiful than the Me-209. Post 648 appears to show a laminar flow airfoil.

 

[nuuumannn]

and another type

Post #558 is a Mitsubishi Ki-83. Beautiful machine. Note the "US Army" titling under the left hand wing. This was a prototype.
