  • need help to identify the aircraft to this propeller

    hello my name is FALLER PIERRE OLIVIER
    i'm french living in aréa of 'alsace'
    i have found a propeller from the first world war at my aunt (or poofter)
    sorry for my bad english i used a internet translater
    the model is a axial from Berlin.
    in a first time i think it's a propeller from a Fokker dr1 but a man tell me that's it's not possible because Fokker have no 200ps.
    i would like to know which aircraft it comes?
    thank you for your help.
    the plane would spit between the village of 'dambach-la-ville'and 'scherwiller' in france in the area of 'alsace'

    of the propeller there is written:
    4493
    axial
    berlin
    200ps benz D292 ST190
    TP 127

    by looking at the different model I have noted that some had a kind of shroud on the nose of the plane and my helix appears to have traces of wear to refit

    Bonjour Pierre,

    Welcome to the forum.

    The data on your prop translates as;

    4493 Axial's serial number
    Axial The maker
    Berlin The maker's location
    200ps Benz the engine, 200hp made by Benz
    D292 Diameter in cm
    ST190 The pitch in cm
    TP 127 Axial's type number

    Your prop was made for German C Class aircraft, which were two-seater armed biplanes with an engine of more than 150ps.

    German propellers were not designed and made for a type of aircraft, which is what the French and British did, but for a class of aircraft, so your prop could have been fitted to several types. Known examples are;

    DFW CV
    LVG CV
    Junkers JI
    Albatros JI, C VIII
    Rumpler C III
    Halberstadt C V

    With kind regards,

      thank you very much for your help bob.i had already identify different data one of your precedent post on the forum.i would like to know if there is a way to know specifically what type of aircraft it's thanks to the shape of the trace cache nose of the plane?

        i don't really understand what is the 'pitch' désignation.
        it's the inclination of the propeller?

          Pitch is the theoretical distance the aircraft will move through still air in one revolution of the propeller.

          The reason why the data is on both the hub and the blade is because if a spinner, also called a nose cone, was fitted on the hub, the data on the hub would not be visible, so it was repeated on one of the blades.

          It is not possible to link your propeller to a particular make of aircraft, only the class, C.

          My list below is of aircraft that I have recorded with a type 127 Axial prop. Some makers appear to have fitted a spinner to every aircraft (such as the Albatross C VIII). But other makers such as LVG, fitted a spinner to some Class C aircraft but not all. I have not seen a photograph of a Halberstadt CV with a spinner, but this does not mean that all these aircraft were made without a spinner.

          DFW C V spinner
          LVG C V some
          Junkers J I spinner
          Albatros J I some
          Albatros C VIII spinner
          Rumpler C III some
          Halberstadt C V none known.

          Your propeller can only be described as from a C class aircraft.

          With kind regards,
