Default Garuda and Heine propeller

Hello, I have two German propeller found a Garuda from the First World War. He is 2.80 meters long and has the following inscription:
Geprüft FLERS ABT2
Garuda propeller
DRP No. 5354
150 hp
Benz 6.6
D 280 blattbr. 0.25
Stg 188
train

the second propeller is a Heine 3.0 meters long, I think from the twenties?
with the caption:
BMW 5a
D300
H185
Heine
50397

motor 5a
diameter 3000
pitch in 1850

My question is now from which aircraft are the 2 Propellers
Best regards and many thanks
Thomas

Gruß Herr Bär!

Your Garuda Propeller dates from c1915 and was used on aircraft such as the AEG C II and the LVG C I. The Benz engine was much used by the Imperial German Navy but in this case it was from an Army aircraft.

The Heine propeller dates from c1930 and was intended for the BMW 5a engine. The hub may have been fitted for a Rupp quick release hub. The BMW 5 engine was a V12 engine of about 400hp which was used on aircraft such as the Albatros L3 and L5.

I'm guessing that the Garuda had decals at one point?

Greetings Dave,

Garuda propellers did not always carry decals. I think this is the case for all WW1 makers from all the warring nations. Photographs of stored propellers generally show only an occasional decal, perhaps (off the cuff) at ratios from 10:1 in one example to 50:1 in another.

In the last year of the war the Germans ran out of the materials to make the lacquer they applied to props and also the dope they applied to the aircraft fabric. They made a synthetic cellulose by boiling potatoes and reducing the starch to something like cellulose. It appears not to have worked on propellers because the handbook issued by Idflieg for use at unit level stated that props were to be stored lightly greased with a thin grease, which was to be wiped off before flight and replaced with a thick grease, which gave some protection against rain and hail, important because the combined velocity of the prop tip and driving rain could approach supersonic speed.

Axial propellers had a distinctive art-deco use of alternating laminations of dark and light coloured wood. Towards the end of the war this vanished and Axial props became a uniform black. This might well be because of applied grease.

With kind regards,

Bob

Default Garuda & Heine Propeller

Hello, I want to say thanks for the information on my two propellers. The Garuda and Heine propeller. I still have two questions.
Is it possible that the Garuda (the propeller has no decal) comes from the AEG CII, because it has 150 hp? the 150 PS ist written on the propeller
The LVG CI had only 120 hp?
I find no pictures of Albatros L3 and L5 in the web, i will get happy to get one picture from the aircraft. Many greetings and thanks Thomas

Thanks, Bob. I always liked the Garuda decals and assumed they were on all of their propellers. Decals certainly add a touch of "elegance" to the props.

Fozzie,

I have done some research and can confirm that the LVG C I did use the 150ps Benz engine. The pre-war C I used the 110hp Benz. From 1914 onwards the 150ps Benz engine was used.

Bob

Hi Bob, thanks for your help and the information on the propellers.
If I copy images from the albatross L3 and L5 I'll put them in the forum.
Greetings from Germany Thomas
