    Constant chord wing query

    Hi All,

    I have purchassed a plan of a 78" wingspan Katana, on the wing plan there are 2 different wing types. One is for a constant chord wing and the other is for a tappered chord wing. My query silly as it may sound is what is the difference between the two and how do they effect the flight.

    Regards

    RE: Constant chord wing query

    Great question. I have an uneducated opinion that I'll keep to myself. Looking forward to some experts "sharing".

    RE: Constant chord wing query

    Constant chord wings have better stall and post-stall characteristics but poorer roll rates and have poor snap characteristics. Think of military warbirds in combat. They all have tapered wings. I would think it is more difficult to design a tapered wing with good stall and post-stall characteristics, but well designed tapered wing will have better roll and snap characteristics.

    My two cents.
    With airplanes, keep the pointy end going forward as much as possible.

    RE: Constant chord wing query

    Thanks ggraham500 that does make a lot of sense. So I will use the tapered wing section then.

    Great experiment! Build both wings then report your findings to see if they agree with published data.

    RE: Constant chord wing query

    Thanks for the interesting comments and there was me thinking that it was a silly question.

    Build both wings now there's a thought, hmmmm. that would be one way to determine what the different flyingcharacteristics would be.

    regards
