Albatros D.V mit 100u120 P.S

[Koloman Mayrhofer]

hallo,
the D.D. stands for Doppeldecker (biplane) . so that make sense as the 120 hp engine was a common sight in B type planes.
the designation L.D.D. can also be found in documents. this stands for Land Doppeldecker (land biplane).
i have found this designations in documents from 1914 to 1916 not later.

cheers

Hello Glenn,
welcome to the forum !
As someone already posted the PS means Pferde Staerke, same as HP for horse power. Anyway there were differences in measuring hp in Britain and Germany - in England hp is often referred to as bhp, or break horse power, the power you need to stop an engine, However this difference would not be as big as 120 to 150, but merely some 5 hp difference.
Greetings,
Catfish

Hi M,
Thanks for that.
While that makes sense I have to add that it is a stamp and not writing.
there is no extra "0" that is faint and there isn't any room for it between the other "0" and the "U". when I get them in my hands I'll get some scans and put them up for you all to see.
Thanks!
Glenn.


Glenn; I left this alone for awhile and have been giving it a lot more thought that it probably really deserves but one thing has occurred to me is the method that people normally use in doing hand stamping. Which I have done a little of!

If you are hand stamping you normally stamp left to right the same as we are taught when writing script. Lets just figure that he or she just miscalculated the spacing need on the first stamp but they just keep going on the stamping. This is the reason that in cases of stamping in restricted areas one must be careful of the spacing, one slight mistake and its wrong and no space to correct it. It is possible that they should have started from the right side instead of the left.

Yours, M.L. Anderson

u is the short form of 'und' which means 'and'. As the Alb. D V was a single engined aircraft , this means that he was trained in several different Albatroses which used 100 and 120 horse power Mercedes engines.

I can't believe that the smaller sized D.II engine was fixed in D.V's, so the best would be a scan of this writing/stamping.

Glenn sent my a picture of the Flugbuch and asked me to show it here.

It shows that the pilot made his basis training on Albatros D.D (a collective name for several Albatros trainers) with 100 and 120 hp Mercedes engines.

But he was also trained on Albatros B.I, B.II, B.III and C. XII,
on Rumpler B-types and on DFW B-types.

Thanks for that Hans,
that should clear it all up!!!!

i use to race motocross, i have a book on how to fix cycle motors and one part has to do with HP MATH and it says PS is metric HP makes sense dont it

[Hans]

or 1PS=0.73549875 kW.

1 bhp = 1,014 PS = 745,7 W = 0.7457 kW

SAE PS seems to be the same (since 1972).

All taken from Wikipedia, as I my last physics hours where in 1976.

From what I've been able to google the D.V had a 160-180 HP engine so can somebody please explaine what the 100-120 is about if its not horsepower?

thanks

Glenn.

Glenn:
My questions are: what's the trainee pilot's name, at which FEA was the training conducted and when?
TIA, Rick
