About the propeller. The propeller was produced by Włodzimierz Szomański’s factory, Warsaw. Privately owned, presented in Museum of Air Force, Dęblin (July 2018). Pitch markings not clear (corrected?).

Construction. The propeller lamination consists of 9 ash plies. The outboard leading edge of each blade has an aluminum sheathing. The propeller was originally covered with fabric and black Tonkilaque coating. Clearly visible is separation line of canvas previously covering propeller blade; glue print left on the part, where the canvas was removed.

Aircraft and Engine. This propeller was installed on PWS 14 and PWS 16 aircraft. Both aircraft were powered by Skoda -Wright Wirlwind J-5A/B radial engine, rated to 220 HP.

O śmigle. Śmigło zostało wyprodukowane w zakładach Hugo Heine, Berlin-Waidmannslüst. Śmigło było używane, i zakończyło swój resurs uderzeniem o ziemię jedną łopatą. Śmigło posiadało niekompletne oznaczenie producenta na piaście (brak dwóch doklejanych lameli z informacją o producencie silnika i jego mocy). Zachowały się natomiast oznaczenia średnicy (D-256) oraz skoku (H–205), a także stempel Heine, oznaczenie STANDARD i GEPRUFT FLZ. Liczba szpilek mocujących: 8. Śmigło w zbiorach prywatnych.

Budowa śmigła. Śmigło złożone z ośmiu lameli, w kolejności (prawdopodobnie):orzech, jesion, orzech, orzech, mahoń, orzech, jesion, orzech.Przed sklejeniem warstwy drewna były specjalnie żłobkowane dla zwiększenia powierzchni klejenia.

Samolot i Silnik. Śmigło napędzało  9-cio cylindrowy, 100-konny rotacyjny silnik  Gnome 100, lub jego licencyjną niemiecką wersję Oberursel U.I Silnik miał 95 cm średnicy i 107,4 cm długości,  suchy ważył 137,4 kg. Pojemość silnika 16,303 litra. Ciężko dziś dopisać możliwą historię śmigła powiązaną z miejscem odnalezienia t. j terenami  Wielkopolski. Silnik Gnome 100PS wyprodukowany w Niemczech na podstawie przedwojennej  licencji w zakładach Oberursel  używany był w kilku typach niemieckich samolotów , między innymi Fokker EII,  Fokker E III,  Pfalz E II. Nie udało się ustalić się choćby prawdopodobnego zastosowania śmigła do któregoś z samolotów.

About the propeller. The propeller was produced by Hugo Heine’ workshop Berlin-Waidmannslüst, Used, its airworthiness ended when the tip of one blade was damaged by hitting the ground. The markings are uncomplete, The missing data is the engine type and the power.  The rest of propeller markings is there: diameter (H-205),the diameter (D-256), as well as the Heine Stamp, STANDARD and GEPRUFT FLZ.  Number of bolts: 8. Privately owned.

Construction. The propeller lamination consists of 8, plies:  walnut, ash, walnut, walnut, mahogany, walnut, ash, walnut. Plies sulcated before being glued to increas the area.

Aircraft and Engine. The propeller was working with 100 HP anti-clockwise (front view) rotary Gnome 100 or licence built Oberursel U.I engine. Engine dimensions were: diameter – 95 cm, length – 107,4 and the dry weight – 137,4 kg. The engine was used in Fokker EII,  Fokker E III,  Pfalz E II aircraft. Nowadays it is hard to find any plausible history related ot the propeller and the area of Poznań, where it was unveiled

About the propeller, The propeller was produced by WSK -4 of Warsaw factory (WSK stands for “Transportation Equipment Entity” the new neme hiding partialy military production), most likely shortly after moving the production from LWD Łódź, The way of prop marking was changed ; PLAT – PIPER, SILNIK – CONTINENTAL , similar to the way it was done during pre war period. As Other Piper’s props  this is an exact copy of US Sensenich propeller. Serial number indicates manufacturing date of 1951 most likely. Propeller in hands of MLP Cracow, out of the official exhibition (2016).

Construction, The propeller lamination consists of five ash plies. The outboard length of leading edge of approx. 600 mm and the tips have brass sheathing, while tips on the length of approx. 310 mm are covered with painted fabric (red tips colour could be given during subsequent renovation works).

Aircraft and Engine, The propeller was used as a “replacement” with one of ex-US Army Piper L4 Cubs, which were purchesed by Poland after WWII. The propeller was working with 4-cylinder Continental A-65-8 engine, boxer layout. Engine cubic capacity – 2,8l.

About the propeller

The propeller was produced by Warsztaty Centralnych Zakładów Lotniczych in Warsaw. Polish aircraft manufacturer.

Construction 

The propeller lamination consists of nine ash plies. Diameter of propeller is about 270 cm and the pitch is 240 cm. The propeller has not metal sheathing on leading edge.  The propeller is covered with clear varnish. There is characteristic red and white decal with CZL logo on a blade.

Aircraft and Engine

Unfortunately we do not know for which aircraft the propeller was intended. Marking on the hub says that engine was from Austro-Daimler family. Those Austrian six-cylinder, liquid cooled engines (90 to 225 HP) were widely used before and during W. W. I period.

About the propeller, The propeller was produced by Sensenich, USA, but the history is not 100% clear. Decals are most likely retrofit ones. Red coloured tips could be dated from the “airclub’s life” of the prop or a result of the restoration. Red colour covers olive green one.  Model numer is 43K 10107 most likely. In private. Survived thanks to the pilot of the Airclub of Ostrów. Presented here thanks to Jacek Dzienisiuk.

Construction, The propeller lamination consists of five ash (most likely) plies. The outboard length of leading edge of approx. 600 mm and the tips have brass sheathing, while tips on the length of approx. 310 mm are covered with painted fabric (contemporarily paint).

Aircraft and Engine, The propeller was most likely used in Poland with one of ex-US Army Piper L4 Cub. It proves that some of American airscrews kept airworty status. The propeller was working with 4-cylinder Continental A-65-8 engine, boxer layout. Engine cubic capacity – 2,8l.

About the propeller. The propeller was produced by Warsaw factory located on Pola Mokotowskie CZL. Preserved in very good shape: the propeller number and the engine type also  a pitch and diameter markings are clearly pressed on the hub. Also manufacturer’s decals – both CZL marks  are well preserved. The manufacturing date of the prop is missing as it was not a part of the CZL markings, just estimated for the period of 1921-1924. In 1970s purchased by aviator and propeller enthusiast Andrzej Perzyna. Now a part of private collection (2018).

Construction. The propeller lamination consists of 7 plies (20.5 mm thick each) of ash wood. No sheathing fitted, covered by colorless coating.

Aircraft and Engine. The propeller was produced for one of Polish built Ansaldo A-1 Balilla powered by 220 HP inline, 6 cylinder, SPA (Società Piemontese Automobili) Italian engine. Engine’s CC: 14,6 liter, weight ca 240 kg, compression ratio: 5,2.

About the propeller, The propeller was produced by Sensenich, USA. Renovated, polished, painteted contemporarily. Black strip dividing colours added to “imrove” good look. Brownish colour results from either age or painting. Some propeler markings were tarnished during the renovation works, Missing Model numer was 43K 10107 most likely. In private. Survived thanks to the pilot of the Airclub of Ostrów. Presented here thanks to Ireneusz Kuśmierek.

About the propeller. The propeller was produced by Włodzimierz Szomański’s factory Inegrale, Warsaw. The propeller is displayed In Polish Air Force Muzeum of Dęblin (october 2017), Borrowed from Museum of Puck. Decals in rather poor condition, however a Tonkilaque coating is almost perfectly preserved.

Construction. The propeller lamination consists of 8 ash plies. The outboard leading edge of approx. 500 mm (measured along diameter) has brass sheathing (non standard, most likely due to Marine application). The propeller is covered by black laque.

Aircraft and Engine. The propeller was used with one of Polish Leo 135 seaplane. Engine: Hispano Suiza 180 HP.
