FB entry of famous aviation histographer Robert Gretzyngier. Picture taken during Lublin Fairs Militaria on 19.10.20109. It looks like someone is in possession of a half of Szomanski propeller designed for polish built LWS 3 Mewa observer aircraft. Congratulation!
Nicely renovated propeller of TS-8 Bies. The peculiar thing is the first brass sheathing element, while the other elements stay aluminium. Most likely renovation result. Photo: Karol Borys. Thank you!
One of the first German propellers maker. The company was founded in Berlin by Karl Mohn, born 1887. At the age of 24 Karl acquired his pilots’ licence No. 188. The first reference of his propeller making company is dated back to 1915. According to Inter Allied Control Commision only 3800 props were maby by Karl Mohn and his son’s factory. Propeller production was terminated after WW. I.

|Engine||Hispano-Suiza 150 HP|

About the propeller. The propeller was produced by French Chauvière Intégrale factory. Currently on exposition of Muzeum Morskiego Dywizjonu Lotniczego in Puck, Poland.
Construction. The propeller lamination consists of eight plies (probably ash). Diameter of propeller is 272 cm and the hub thickness is 150 mm. The propeller has metal sheathing on outer part of leading edge. The propeller is covered with black Tonkilaque. On both blades the decals with company’s logo are placed.
Aircraft and Engine. The propeller was intended for eight-cylinder inline V Hispano-Suiza type 8Aa engine 150 hp. The engine having 11,76 L capacity was rated at 150 hp at 2000 rpm. It had 4,7 compression ratio, 120 mm bore and 130 mm stroke. In Poland this engine was powering Shreck FBA-17 HE hydroplane used by Morski Dywizjon Lotniczy (Sea Air Squadron) at Puck. Six aircraft were delivered in Spring 1926. The last of Schrecks (wearing No 4-4 on fuselage) was in active service until 8th of September 1939 when it was destroyed by servicemen after German air raid.

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.

Heine, typically for that period was a cabinet maker before picking up propeller production. Established by Hugo Heine workshop was located several premises in Waidmannslust Berlin. By 1914 the company trade mark “Heine Propellers” was registered. A growing demand of WWI aircraft production resulted in some 36.000(?) propellers produced at that period,making Heine the largest producer of German airscrews. Thanks to the big number relatively many of them survived to contemporary times.
The history of Heine propellers were continued during the mid war times. Many of german and not only german aircraft were bearing Heine propellers. Heine contributed also to the WWII effort.
Heine in Poland Polsce. Obviously, Heine propellers were used in Poland after regaining independance in 1918; That concerned some propellers installed on captured aircraft, damaged, and stored in warehouses (like it was in Poznań – Ławica).
Mid war Times saw Heine propellers also installed on some Polish new – designed aircraft, ordered directly at manufacturer. That was untill the German – Polish political tension stopped the deals.
After WWII the history re-occured, and german capured aircraft, like HE 72 Kadett cor FW 44 Stiegliz, were fitted again with captured German propellers including Heine, some of proppeelers were fouund as used or spare parts.

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
