Heine, Germany

 

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

The propeller of the Lublin R.XIII SP-AMG aircraft. The picture was taken during airfair flights in Sweedish Stokcholm – Bromma airport in 1936.
The propeller has a non standard feature: polished leading edge aluminium sheathing (the tonkilaque coating had been removed), most likely to improve the image of the demontrator aircraft.

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.
