Excellent work as usual my dear Apophenia,


and I can add;


PZL-Y,T-200,T-400,T-600 were a projects for 8-10 passenger transport aircraft,powered
by different engines,in 1928.


PZL-57 was a bomber/recce aircraft project,developed from PZL-46,(not 100% sure,I will check).

Škoda/PZL WS-1 Original Engine Designs - 1928-1939

The radial engine designs by Stanisław Nowkuński had US-style designation applied. For the Skoda/PZL engines, displacement was given in cubic centimetres. The prefix 'G' stood for silnik Gwiazdowy (Radial engine), 'R' was for radials with a Reduktor (Reduction gear).

The US-style engine designation system was probably abandoned at the time of Stanisław Nowkuński's death. No such designation was applied to his last design, the named Foka.

With the late 1930s change to names-only, engines were given the names of water mammals. This was changed for later radial engine projects which received reptile names.

Skoda G-594 - 1930 120 hp 7-cyl* air-cooled radial

- PZL G-1620B Mors B: 410 hp (470 hp T/O)

[Boogey]

PZL (Państwowe Zakłady Lotnicze) Numerical Aircraft Designations - 1928-1939

PZL-21 - [??]

PZL-25 - [??]

The PZL-21 probably was a concept of single-seater fighter / fighter trainer aircraft, based on the PZL-20 racer.

The PZL-25 was a concept of heavy escort fighter with a rear turret armed with 20 mm gun, based on the PZL-23 Karaś.

The PZL-62 is a wrong designation and in fact it's referring to the PZL-55.

The PZL-63 is a wrong designation and in fact it's referring to the PZL-53 Jastrząb II.

 

[hesham]

Amazing Info my dear Boogey,many thanks.

 

[Boogey]

I'm very sorry, I don't know what I was thinking about when I wrote such silly things of the PZL-21 designation. I still don't know anything about that aircraft.
I meant the PZL-20 fighter based on PZL-19. Apophenia has placed both types on the list.

Many thanks for the additions and corrections Boogey

Ryś means in English Lynx ;
Żbik means in English Wildcat ;
Miś is in fact a diminution of Bear and You all can call the bomber a Bruin.

That is the 1938 PWS.33 Wyżeł ('Pointer') and, to my eye, a fine-looking design. PWS was put under state-run PZL in 1936 ... and, as a result, PWS designations often get conflated with PZL's. (BTW, there was a PZL.33 but it was quite a different design.)

Two prototype Wyżeł were built. The PWS.33 was intended as a crew trainer for the PZL.38 Wilk fighter-bomber. Span was 9.26 m. Powerplants were 130 hp PZInż Major 4B inverted 4-cylinder engines.

Today in Facebook a post by Patrick Bruyneel whom I trust does his homework very well. He may even be a member here.


PZL-330 1996 (Poland) Light attack plane.
Although funding for the work on the PZL-230 F ′′ Scorpio ′′ was stopped in 1995-1996, PZL tried to develop a new project for a cheaper attack aircraft from its base. In fact, work was going back to 1991 when options for turboprop aircraft were considered. The PZL-330 was of small size and was seriously simplified compared to its ′′ big brother ". The motorization consisted of two TVD turbo-propellers with propellant propellers. His payload dropped to 2500 kg, with only six take-out points for the bombs. The armament consisted of an automatic 30 mm gun placed in a container installed under the fuselage. In addition, the possibility of equipping a container with a no-back cannon was considered. The PZL-330 has received a V-shaped tail, according to designers, making it easier to control at low speed. Despite the price drop of a half and a half times compared to the PZL-230 F, the project has not attracted interest among the Polish military. In 1997, all work on this ′′ miniature ′′ Scorpio was stopped.
