On the second drawing I read the dimensions as lenght 10.1m. Span of
the wing isn't recognisable, but for the tail plane it's 5.5m, I think. So a
quick measurement gives wing span as13.3m.
Unfortunately speed isn't measurable on a drawing ... ;)

Thanks Skybolt,

I'm currently cleaning up the picture a bit. A lot of work to do on the side view.

"I'm currently cleaning up the picture a bit."
Looks, you are working on the bitmap. Have you tried to
"redraw" it as a vector graphic ?

I've never worked with vector graphics programs save for various CAD programs. Is there anything you'd recommend?

I usually work with paint, drawing ships more than aircraft. I'm just used to it and can use it reasonably well - like below;

The first picture you attached was a re-drawing from the original blueprints that I did for clarity. The J.11 is fictional.

It's so weird my dear Red Admiral,


in an old Polish site,they spoke about this design as a real one,and they
said it involved in a competition of 1939,but unfortunately they switched
all its pages,and many Info was gone.

I could be wrong, but to me all that he meant was that the J.11 drawing was fictional, not the J.11 project itself. It is more of a re-creation based on what is known of the project. Am I right red admiral?

You are right Stargazer,


the Polish site mentioned the J.11 as a light bomber,and absolutely it was a different
design.

Dear,
According to the book "Gente dell'Aria - Giorgio Evangelisti", the Jona 11 project was a 3-engined fast bomber designed in March 1938.
The aircraft should be engined with 2 radial Fiat A.74 in the wings, and a pushing Isotta Fraschini Asso XI (In line engine).
In October, however, Jona designed the J.11/C, a 3-engine fighter based on the bomber design and motorized with 3 Isotta Fraschini AS.L. 121 RC 50.
The projected armament was of 2 machine gun of 12,7 mm, and 2 machine gun of 20 mm, plus 300 kg of bomb; while the performance was calculated in 600 km/h at 6.000 m altitude.
Here the 3-view of the Jona 11/C.
Regards.
