A little more info!

Z-28 was 4-seat utility aircraft designed by eng. Ladislav Marcol in 1947. It was a counterpart for Avia Ae-45 and looked much like twin-engined Z-22 Junak. The engines were Walter Minor 4-III, 105 hp each.
Z-33 named Derviš, also designed by Marcol, was single-seat light sport aircraft with 40-hp engine, reaching 154 km/h maximum speed.
The twin-boom Z-34 was an agricultural design from 1958 by eng. Závrbský. It was powered by two M-337 engines (210 hp each) and could carry 600 kg of chemicals.
Z-36 (1960) was single-seat ultralight aircraft designed by eng. Dobrovolský, with 36-hp Jawa engine.
Z-38 was a project of agricultural autogyro, designed by eng. Jan Mikula in 1963. Powered by M-337, it could carry 300 kg of chemicals.
Z-39 was a two-seat trainer project from 1963, powered by M-137 engine (180 hp), with tricycle gear.
Z-426 and Z-626 - two "missing links" of the famous “Trener” family. The first was light agricultural aircraft from 1960, with Walter Minor 6-III or M-337 engine, carrying 100 kg of chemicals. Z-626 was “simplified” version of aerobatic Z-526AS, with fixed landing gear, designed in 1967.

Z-41 was, basically, the same Z-42 - but lighter, with 4-cylinder M-132 engine instead of 6-cylinder M-137. M-132 was projected as M-332 “aerobatic” version without compressor (it referred to M-332 in the same way as M-137 to M-337). But finally M-132 engine was never produced, and therefore Z-41 also remained on paper. Another unrealized derivative of this family was Z-43R, which was Z-43 with retractable landing gear and (optionally) 250-hp M-437 engine.

Hi all,

...Zlin Z-52 (source: L+K 1987)

From Kryl'ya Rodine 5/1988,


here is the Zlin Z-52 project,with some data.

 

[CostasTT]

Another Zlin-Moravan project I'm aware of is the Z-400, based on the Russian Technoavia Finist, but with a Canadian Orenda OE600A V-8 600hp engine. There was even a photoshopped picture of a border guard SM-92 Finist with the Orenda engine.

[hesham]

Great find Costas.

 

[Jemiba]

Could one of our native Russian speakers please translate, or give a short summary
of the text about the Z-52 ? My main questions: Is the canopy really circular, maybe
for better ground observation ? The model seems to show no sign of such a shape.
And is that low wing aircraft a derivative ?

 

[Granit]

Very little information. Short description of technical characteristics. The figure below shows the Fournier RF-8

 

[hesham]

Thank you Granit,


and what about circular canopy.

 

[Granit]

Absolutely nothing is said.

 

[hesham]

Thanks.

 

[Jemiba]

Many thanks indeed, Granit.
Made a comparison of upper and side view and that circular canopy just seems not actually to be
a part of the Z-52. and in Maverics post, it seems to be more a kind of earmark anyway.

Hi,

I want to explain the difference between Z-135 and Z-135 Crane drawings.

Hi,
the project of the engineer Mikula from 2001, who was a chief engineer at Moravan Otrokovice (Zlin) for many years. He led the development of the Z-35, Z-40, 42, 142 and Z-50.

[Maveric]

No more information about the Mikula-Project?

 

[Sarastro]

No, the picture was given without further specification in the L + K magazine in connection with the death of Mr. Mikula.

 

[Maveric]

ok...

Interesting how he incorporated several contemporary concepts into a high-wing business jet.
First question: why a high-wing?

Note that the cabin pressure vessel is a simple cylinder with the wing structure completely outside. Then Engineer Mikula added a wing root, streamlined box to fair the wing roots into the fuselage ... common on low-wing passenger jets. We wonder why the entire main-wing trailing-edge is swept when most jet airliners now have flaps perpendicular to airflow ... for better lift at low-speeds.
They still needed landing gear sponsons to install LG outside the pressure cabin.
The V-tail was used on a few other light jets like Vision Jet, Cirrus Jet and Jet Sonex.
The V-tail surfaces look big enough for cruise, but we question if they are large enough for low-speed control, considering the short tail moment arm.
