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
-- http://www.airwar.ru/image/idop/other1/bm4/bm4-4.jpg
-- 2v: http://www.samolotypolskie.pl/uploads/Products/product_440/Bartel_BM-4h_rys.jpg

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
-- http://www.samolotypolskie.pl/uploads/Products/product_2267/preview_stemal.jpg

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-101 - 1937 single-seat gull-wing competition sailplane
- PWS-101: Fitted with ballast tanks, air brakes, span 19.0 m
-- PWS-101 designed to participate in 1937 Rhön-Wasserkuppe

- PWS-103: Designed specif. for 1940 Helsinki Olympic Games
-- Two PWS-103 prototypes completed by Soviets 1939/1940

___________________________________________________________


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. 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
-- http://www.samolotypolskie.pl/samoloty/1824/126/M-9
-- 3v: http://www.airwar.ru/image/idop/law1/m9/m9-1.gif


___________________________________________________________


PWS 'U' Aircraft Designations

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

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.

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.

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.

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.

Page 392 in edition II, Bellona SA, Warszawa 2003 - 2014, KOŃCOWE MISCELLANEA, Oznaczenia typów samolotów przez wytwórnie
- Podlaska Wytwórnia Samolotów.
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 ).

@ Apophenia
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.
