  • How Two Propeller Halfs Become One

    I came across this statement in the material section of the website.

    "American Propeller Company (Paragon) devised a method to balance half-blades individually, then join these at the hub".

    This assembly system has sparked my interest.
    Does anyone have any pictures or documents showing this type of construction? I am curious how they held the two haves together in the completed assembly.

    Thanks,
    Tom

    Tom,

    What Paragon did was match laminations of wood, then glue them together to even out the variations. I think I have the brochure that describes it and I'll try to post that here.

      Attached is a photo of the Paragon 3 blade hub scheme. Of course the 2 blade was much simpler.

      And here's the blurb from a 1920 Paragon brochure about their wood matching process:
