    XLT

    anyone have a set of plans for the Bridi XLT ? need the root and tip airfoil for wing and stab.. plus the layout of the wing and stab...

    RE: XLT


    Scott,
    The tip airfoil is not on the plans; Root airfoil would also be in question if taken from plans since they were not drawn for cutting.
    I have at least one set of original cores here though plus canopies. Are you planning a build?

    Well that’s good, I had pulled them out to trace the airfoils but if Paternguy has them even better.

    Paul,

    I still might need the tracings, I will let you know.

    I have an XLT kit in my stash. I could get a set of profiles from the cores if you like.

    RE: XLT

    Maybe if someone could identify what the airfoil was, that might make it easier. I am sure it was probably just an NACA 0015. This info would be better anyway, so when you make your templates or get your foam cut, the airfoil will be accurate and not a trace job. Many of the foam cutters offer the NACA series as standard.
    Let's just say, they will be satisfied with less. " Ming the Merciless

    Steve.. Yep I might need those tracings to check with my airfoil program and make the templates and cut the wings..

    Scott,

    drop me a line in reply when you can. Since you will be cutting XLT cores, my email may be somewhat related.

    Regarding airfoils, would it not be possible to extract these from the fuse side plan? One would need to compensate for the sheeting and such as well as for the planform but it sounds doable.

    Maybe Paul managed to get you something.

    David.

    RE: XLT

    Scott,

    Here you go. I made these templates right off the XLT plans as mine show the dihedral locations on the side view. I am speculating that the oulline for the wing tip and stab tip ribs represent the actual size.

    The plans call for 1/16" sheeting which is represented on the attached templates.

    RE: XLT

    Bryan,

    Airfoil of the root looks like n64015a (more exact n64014.5a).
    The airfoil of the stab also looks like n640xxa but not so exactly as the wing.
    Tip airfoils? Not yet verified. Who knows?

    Wow.

    How do you guys know this stuff??

    Wouldn't it be funny if Mr. Bridi simply drew out the profile, independant of airfoil NA numbers, etc...

    RE: XLT

    They trace it out and find which published airfoil it fits. A lot of models use airfoils traced off the side of a size 11 wingtip dress shoe!

    Brian.

    Redesign and reconstructing a model is as important as designing a new one IMO and there are more important reasons to find out the original airfoils.

    First the right dimensions of airfoils can be very important, especially these of this model and with fully sheeted wings. When using a NACA 24xx we have a much easier job to do, not so critical.

    Knowing the basic airfoils we also can print all individual ribs with an Excell program and when some parts are lost, reconstructing them is easy.

    Old plans are often copies of copies or we see not accurate airfoils examples of a kit.

    There can be a difference between root and tip airfoil, part of design consideration of the designer.

    To show the difference between two of them, NASA Langley 64 012 and 64 012A: Cutting with a too hot wire and you make the 64-012 instead of the 64-012A LOL
    After some time you can read an airfoil like a character.
