PWS (Podlaska Wytwórnia Samolotów) Aircraft Designations

I've made a start on a PWS designation list - relying heavily upon listings in the Samoloty w Lotnictwie Polskim website - http://www.samolotypolskie.pl/

As usual, there are plenty of gaps to fill! Additions and corrections welcome.

PWS Aircraft Designations

PWS licensed-built a number of aircraft designs. These included a range of Potez biplane reconnaissance bomber - 35 x Potez XVA2, 150 x Potez XXVA2, and 155 (sources vary) x Potez XXVII. PWS also took over development of the Bartel BM-4h biplane trainer when the 'Samolot' (Wielkopolska Wytwórnia Samolotów) firm failed after a factory fire.

Bartel BM-4h 2-seat biplane primary trainer, licenced x 50
- BM-4h: Prototype, 1 x 120 hp DH Gipsy III 4-cyl inline
- BM-4h: Series, 1 x 120 hp Walter Junior 4 4-cyl inline

One license-built aircraft that did receive a designation of sorts was the Avia BH-33 biplane fighter. Polish examples of this Czech fighter were designation PWS-A - 'A' for Avia.

Un-numbered PWS Aircraft Designations

PWS-A - Avia BH-33 biplane fighter, licenced 1929-30, x 50
- PWS-A: Skoda Jupiter VII 9-cyl radial, span (upper) 8.9 m
-- Should have been PWS-9 but 'A' for 'Avia' used instead*
-- * See Boogey's Reply #11 (below)

The unbuilt Stemal VII project was brought to PWS by its designer, Stefan Malinowski. The later designation style, PWS-Stemal VII, suggests that PWS also regarded this airliner concept as a potential license-built design.

PWS-Stemal VII - [Project] 1928 high-wing monoplane airliner
- Stemal VII-PWS: Init. designation, 1 crew + 4 pax
- PWS-Stemal VII: Final designation, Dural const., span 10 m
- PWS-Stemal VII: 1 x 220 hp Skoda-Wright J5 Whirlwind

Numbered PWS Aircraft Designations

Most PWS aircraft designations followed a simple numerical sequence. But there were examples of type numbers being reapplied. Most Polish sources show the designation style as PWS-xx, with the type number separated from PWS with a hyphen. Other publication use a space or a period.

Some PWS designations are shown with French-style alpha-numeric role/crew number suffixes. This seems to have been a Lotnictwo Wojska Polskiego (Polish Air Force) practice rather than a PWS style. PWS sub-type suffices are usually letters (sometimes small letters, sometimes capitals).

Designers names were sometimes acknowledged in later designations. 'M', 'U', and 'Z' designations are explained below the Numbered PWS Aircraft Designations listings.

One anomoly in the 'M' designations is the PWS-17 night fighter project which was also refered to as the PWS-17M2. But, at times, it is listed as the PWS M-2. The PWS-17M2 designation is clearly a Lotnictwo Wojska Polskiego French-style role designator. But the 'M' in M-2 is clearly _not_ a reference to inż Józef Medwecki. See Boogey's Reply #11 (below)

PWS 'MN' and 'M' Aircraft Designations

The PWS 'MN' aircraft designation is for technician Józef Medwecki and inż Zygmunt Nowakowski. The MN-4 sequence is actually a follow-on from a WWS Samolot designation - MN-3 (included below for completeness). The MN-4 predates the 'M' series (below).

WWS Samolot MN-3 - 1928 4-seat parasol sports a/c, x 1
- MN-3 : Open cockpit, tandem pairs of staggered seats
- MN-3 : 1 x 45 hp Anzani 6-cyl. 2-row radial, span 11.00 m
- MN-3 : Wooden wing/tailplane, steel-tube fuselage constr.
-- Built for 1928 Polish Konkursu Awionetek contest
-- Anzani engine failed & MN-3 was retired; conv. to MN-4

PWS MN-4 - 1933 2-seat, single-engined parasol tourer, x 1
- MN-4 : MN-3 with fwd cockpit seats removed (in 1932/1933)
- MN-4 : 1 x 85 hp Cirrus III 4-cyl. inline, span 11.00 m
-- http://www.samolotypolskie.pl/samoloty/1828/82/MN-3-MN-42

PWS 'M' aircraft designations are for designer Józef Medwecki. Only two designs are definitely attributed to Medwecki - the PWS M-8 and M-9.

I have included the 'M-2' as a possible alternative designation for the PWS-17M2. This is probably incorrect since the PWS-17 was designed by Zbysław Ciołkosz and Antoni Uszacki, not by Józef Medwecki. See Reply #11

PWS M-2 - (Project) Tandem 2-seat parasol night fighter
- PWS M-2: Same as PWS-17 monoplane night fighter project

PWS M-8 - (Project) 1935 shoulder-wing 2-seat obs./recce a/c
- PWS M-8: 1 x radial, retr. u/c, low-placed vert. tail
-- PWS M-8 was an unsuccessful competitor to LWS-3 Mewa

PWS M-9 - 1939 2-seat light sports high-wing monoplane, span 11 m
- M-9: 1 x 85 hp Cirrus III, Pol AF liaison after Sept 1939
-- M-9 design (with Władysław Kiryluk)* infl. by PWS-52
-- NB: M-9 may be amateur build, thus not attributable to PWS

PWS 'TW' and 'U' Aircraft Designations

Another inherited designation was TW-12 from the designer Henryk Toczołowski with Józef Wulf. The airframe was built by PWS (with the cooperation of the PWS Aviation Club). Tests by the IBTL, Warsaw, revealed low-speed handling problems, resulting in the sole TW-12's conversion into a single-seater.

TW-12 - 1933 Low-winged monoplane single-engine sports a/c, x 1
- TW-12 : (As built) Tandem 2-seater, ply-covered wooden constr.
- TW-12 : 1 x 80 hp Armstrong Siddeley Genet, span 10.50 m
- TW-12 : (As mod.) Forward cockpit blanked off, rudder enlarged
-- http://www.samolotypolskie.pl/samoloty/2999/87/TW-122

PWS 'U' aircraft designations are for designer Antoni Uszacki.

Antoni Uszacki collaborated on a number of PWS designs. Solely attributed to Uszacki were the PWS-18 trainer, PWS-19 and PWS-52 light aircraft, and PWS-54 airliner as well as several unbuilt projects - the PWS-17m2 night fighter, PWS-22B3N bomber, and PWS-23 bomber/transport. Only a 1934 unbuilt project for an observation and liaison aircraft received a distinct designation - PWS U-6.

The 'U' in PWS U-6 is obviously for Uszacki but this designator does not seem to have been applied to any other Uszacki-designed PWS aircraft.

PWS U-6 - (Project) 1934 parasol observation/liaison, span 14 m
- PWS U-6: Proposed repl. Lublin R.XIII, reduced scaled PWS.19
-- PWS U-6: 1 x 430 hp PZL WS-G-1620B Mors II 9-cyl radial

Excellent work as usual my dear Apophenia,

and I can add one this,as I know the PWS-105 was also a sailpane,no more details,but
I will check.
 
Thanks Hesham. Interesting to hear about a PWS-105 ... must be a PWS-104 too ;)

My dear Apophenia,

I will check about that too.
 
Hi Apophenia, excellent work. I've checked the pdf file wrt PWS-49, you're right, Odr is just the beginnig of : Odręczny tekst pot wycinkiem
trudny do odczytania = Hand-written note under [well, actually "unter" ;-)] the scrap, hard to decipher. The timescale mentioned in the the text (Nov 1929) strongly suggests simply PWS-4, so the designation PWS-49 probably did not exist at all. Best, K.
 
Thanks for checking that klaud3. There are a range of PWS-5x designations in 1930. But, I think that you are right ... this 'PWS-49' is a garbled reference to the PWS-4.
 
Hi,

Mr. Stefan Malinowski designed the MAL,it was a two-seat cantilever high-wing monoplane light
bomber Project,powered by one 450 hp Lorraine-Dietrich engine,co-operation with PWS.

http://www.samolotypolskie.pl/samoloty/1780/82/MAL2
 
Thanks Hesham. Always interesting to see mjr inż. Malinowski's name pop up!

So, MAL was an IBTL (Instytut Badań Technicznych Lotnictwa) project. I suppose if it had gotten further along in development, MAL would have been given a Stemal name or, if headed towards production, a PWS designation.
 
Yes my dear Apophenia,

and in Stemal designation;

PWS 'M' Aircraft Designations

PWS 'M' aircraft designations are for designer Józef Medwecki. Only two designs are definitely attributed to Medwecki - the PWS M-8 and M-9.

I have included the 'M-2' as a possible alternative designation for the PWS-17M2. This is probably incorrect since the PWS-17 was designed by Zbysław Ciołkosz and Antoni Uszacki, not by Józef Medwecki.

PWS M-2 - [Project] Tandem 2-seat parasol night fighter
- PWS M-2: Same as PWS-17 monoplane night fighter project

In case of the PWS-17 M2 fighter project the letter M means simply " Samolot Myśliwski " ( Fighter Aircraft )
and the number 2 - Dwumiejscowy ( Two-seater ). For example original designation of the PWS-10 fighter was PWS-10 M1 ( Single-seater Fighter ).
In fact properly designation of the PWS-A ( Avia BH-33 ) fighter should be PWS-9 as it was the ninth construction made in the PWS factory,
but it was decided to state that the airplane is licence-built of the Czech Avia project.
 
Nice Info my dear Boogey,

and can I ask why the company jumped to numbers 50 & 60 during its early series ?.
 
I am going to answer You with pleasure after the laptop of my friend gets loaded, my eyes will rest a little bit
and my awkward translation of the matter from " Samoloty Wojskowe w Polsce 1924 - 1939 " by Andrzej Morgała from Polish to English will be done.
 
Thank you my dear Boogey,

and I have this book,but could we find the answer in it ?.

I hope You know a person speaking Polish who would help You translate the designation systems of the PWS aircraft.
Generaly there were two changes of the system. Therefore the matter is very complicated and full of inconsequences.
Fifties series were provided for sporting & liason airplanes ( sporting PWS-50, PWS-51, PWS-52 ; I think PWS-54 has its designation
as the evolution of PWS-24 ) and sixties for hydroplanes ( PWS-60, PWS-61, PWS-62 ).

PWS-30 - [Project] 19?? passenger a/c, no details
-PWS-30: Designed by Zbysław Ciołkosz
-- http://teatrnn.pl/leksykon/node/1905/zbyslaw_ciolkosz_1902–1960

It's passenger PZL-30 which became the PZL-30 B / LWS-6 Żubr bomber.
 
Projekty i koncepcje
W okresie przedwojennym był twórcą lub współtwórcą koncepcji i projektów m.in. dwumiejscowego eskortowego samolotu myśliwskiego PWS–1, pasażerskiego PWS–30, sportowego PWS–52, liniowego PWS–19, pocztowo-pasażerskich PWS–54 i PZL–27, pasażerskiego PZL–30, bombowych LWS–4 i LWS–6 oraz sanitarnego LWS–2 i obserwacyjnego LWS–3 „Mewa”.

from " Mała encyklopedia lotników polskich " by Jerzy R. Koneczny and Tadeusz Malinowski, Warszawa 1983, the book quoted by Apophenia.

There is one numeral fault in designation of the PWS-30 as it should be PWS-20, after all an aircraft designed by Ciołkosz.

Thanks for that Boogey. Changes made
 
Hi first of all that was excellent work on the PWS designations by all, especially Apophenia. However I have one correction that should be made. On the PWS-23 the net page reference at the end should be http://www.samolotypolskie.pl/samoloty/2240/84/PWS-232 not as listed above, which is actually a repeat of the previous PWS-22 entry.
 
Picked up another anomaly I'm afraid. The Z-47 is listed as a two-seat trainer version of the Z-17. However http://www.samolotypolskie.pl/samoloty/2273/84/PWS-Z-47 states that it is a single seat aircraft, which I would justify as making the aircraft an advanced trainer, similar to the way that something like the MS230 or the Fury (biplane) was used later on in their careers.
 
Yeah, it is difficult to square that sideview drawing with a typical 'liaison' aircraft. It looks very much like a combat type. However, we do not actually know what role was envisioned for that design.

Was that variable-geometry tail design a variation on a theme? Was it the final PWS-37 concept? We really don't know.

And Samolotypolskie does make errors. In one page, they claim that a PWS-37 prototype was actually completed. But, of course, the PWS-37 airframe was never built. -- http://www.samolotypolskie.pl/samoloty/1946/126/Niespal-Jozef
 
The all Infos are here,and we can check from his source.

From his source,

In 1939, the series production of the "Wyżta" and "Ogar" was prepared. In 1939, the designs of the PWS-41 training aircraft by engineer W. Czerwiński and engineer Stanisław Lassota, the PWS-42 fighter aircraft by engineer Z. Jabłoński and K. Nowicki, and the preliminary design of the bomber aircraft by engineer Z. Ciołkosz were created. The design of the PWS-37 liaison aircraft from 1937, developed by the designers of "Ogar", was not implemented.

Thanks hesham. I've added this info about the PWS-36/PWS-37/PW-49 sequence (but left if the conflicting PWS-36/PWS-37 designations. The reference (and link) to the Muzeum Lotnictwa's cryptic 'PWS-49 Odr' I have now deleted.
