Good stuff Hesham ... and very interesting designs.

The Av-40 is obviously a B-135 derivative. And, I presume, the Av-50 was a local rival to what became the licensed Av-14. BTW, if you don't have access to the háček diacritical for the AŠ-82 engine, probably better to use the original ASh-82 (or just Avia M-82). ;)

OT: Does anyone know Avia's internal 'C' designation for the S-92/CS-92 Turbina jets?

Thank you my dear Apophenia,

but I think not for Av.50 which appeared in 1949,but Av.14 designation was
given in 1954.

Here is the Av.38,it was a twin boom high-wing light transport project,powered by two engines driven two pusher propellers,Project only.

The picture #4 is AV-48, not AV-50, according to text.
(corrected, thank you !)

Hi,
project of a light two-seater observation aircraft Avia Av-49 from the end of the 1940s, which better matched the assignment of the competition, which was eventually won by Aero with type Ae-50. Walter Minor 4-III engine.

Hi,
even in the book of Czechoslovak aircraft 1945-1984 by Vaclav Nemecek, this study is listed as Letov LA-P9. I can't determine which designation is correct, maybe I'll find out the truth in the archives of the National Museum in Prague ...

Is there three-view in the Nemecek book?

Hi,
Hesham meant this picture...

Other projects you ask (and not only those) are listed in Bittner's collection, which is stored in the archives of the National Technical Museum. This collection contains approx. 1,600 volumes, so it will probably be difficult to get any details from it. Maybe I'll be lucky ...
