    Hallo, I have a wooden propeller and looking to get some informations about it.

    That's going to be hard, I think. The copper sheathing suggest that it might have been made after WW1, but even that's just a guess.

      Sehr geehrter Herr Gehrmann!

      This prop is most unusual in that it is a pusher prop, indicated by DRUCK on the hub and confirmed by the metal cladding on the tips. There were very few pusher aircraft in Germany in WW1; only the Zeppelin-Staakens and the Gothas, and this prop is unlikely to be from one of them.

      The diameter of 2850mm and pitch of 1580mm indicate that this prop was for a particularly slow aircraft. The engine was probably the 160ps Mercedes engine. And it dates from 1916-1917.

      Almost all German props were made to dimensions laid down by the Prüfanstalt und Werft der Fliegertruppe (the Test Institute and Workshops of the Flying Troops) and published in the P&W Propellermerkbuch but there is no prop listed of these dimensions, which suggests yours is out of the ordinary.

      I have added the details to my database, for which many thanks.

      With friendly greetings,

      Bob

        Dear Bob,

        thank you for these informations. Is it possible that these prop
        was not used in a military aircraft but in a civil aircraft? (Did civil aviation
        exist in this era ?)
        Do you have any informations about the company Behrendt&Rüggebrecht?
        Maybe the producer can help.

        Kind regards
        Thomas
