    Small Continental & Lycoming Availability

    Does anyone know what sort of availability can be expected for the small Continentals like the A-65, C-85, and O-200? How about the small Lycomings like the O-235? What sort of prices could be expected for both new, mid-time, and run out? What sort of overhaul cost? I ask because some of the...

    Positive Cm Airfoils

    I am doing a design study of a delta-wing sportplane and one area I'm getting hung up on is the airfoil selection. I know that the delta planform is relatively insensitive to airfoil choice, but it still requires an airfoil with a positive pitching moment. I've managed to find a few positive Cm...

    Joined Wing Stability and Control

    I have been doing some research into alternative configurations for my project, a single seat, 500 mile range, 150mph runabout. I have done sketches for the normal low-wing monoplane layout (taildragger and tri-gear) and even a rough high wing layout. I would like to explore some other options...

    Fuselage Structure

    I've been researching different airplanes to get a sense of how wood fuselage structures are designed. I see that the Falco has fully curved fuselage bulkheads with longerons at the 12,3,6,and 9 o'clock positions. Plywood skinning makes up the outer skin. I've seen some other planes like the...

    Minimum plywood skin thickness

    I am designing an airplane very much akin to a single seat Falco and I'm wondering if anyone has any thoughts on minimum skin thickness to minimize hangar rash and airshow moron damage? I know that panel buckling criteria are a main driver of skin thickness (though I haven't gotten to the point...

    My design thought process

    I've been tossing around several ideas and concepts for some time. While waiting for payday to roll around so I can order Raymer's book, I have stepped up my research. I'm using this thread to think out loud; comments, suggestions, and opinions are welcome. My concept is a lightweight...

    Design/Production Tolerances

    Here's a question to the aircraft designers here. What sort of tolerances are you designing your parts with? I know that some components require very tight tolerances, but what about stuff like rivet and bolt holes and positioning of brackets and hinge points. I'm familiar with tolerances (and...

    Greetings from South Louisiana

    Greetings all! My name is Chris, and after lurking here for a month or so I finally decided to register and make my first post. I've been a huge aviation nut for all my life. Through serendipity and some careful planning I have gotten to experience many coo things from up-close tours of the B-17...
